Martin Luther's view of sin as a deep problem that enslaves us, versus Erasmus' view of sin as a superficial issue that can be fixed through self-effort, highlights the importance of the gospel in liberating our hearts and leading us to a true understanding of Christianity.

God Saving people out of his sheer loving kindness.

Sounds wonderful. But people needing to be saved because they are otherwise helpless in their sin sounds less pleasing. and we don't like hearing bad news. We don't like hearing bad news, and we don't like giving bad news. But when it comes to explaining the wonderful news of what Christ has done for sinners, It requires that we explain that we are in fact sinners.

Hi, I'm Nathan W. Bingham, and you're listening to the Monday edition of Renewing Your Mind. October 31st. despite many today going door to door to collect candy on that day. Historically, it was known as Reformation Day.

and celebrated Martin Luther's nailing of his 95 theses to the church door in Wittenberg, Germany. As we approach Reformation Day, You'll hear teaching to remind us of the truths that were rediscovered and reaffirmed during the 16th century Reformation. and the importance of getting the gospel right. This week's messages are from Michael Reeves' series Reformation Truths. And we'll send it to you on DVD and unlock the messages and study guide in the Ligonier app.

To thank you for your donation in support of this daily outreach at renewingyourmind.org. Michael Reeves is this week's guest teacher and he is President and Professor of Theology at Union School of Theology in the United Kingdom. Today he will clarify what the Bible says about sin. and how many in the 16th century And even the 21st century get it wrong. Here's Doctor Reeves.

We're going to look now at the question of sin. And see how differently. Sin can be understood. and how different views of sin have profound practical consequences.

Now, Martin Luther grew up with a nipple. View of Sim. It wasn't that he refused to take sin seriously, quite the opposite. Sin, he knew, is the weight that will drag us to hell. It is The cause of all misery, its wages are death.

Yet, while he knew that sin is a severe problem. He didn't think it was a very deep. Problem. It was a view that chimes well with today's cheery optimism. about ourselves and our culture for today.

In our culture we No, we do wrong things, but the suggestion that we might be rotten deep down. It just strikes our society today as utterly repellent nonsense. Uh most believe today we are good people muddling through. And Of course we slip up every now and again. Since the is seen as a small problem, Easy to fix.

And what Luther came to see, surprisingly. Is that such sunny stories of how basically good we are?

so attractive in their cheeriness are actually Terrible. Enslaving lies.

Now, in Luther's day, it was the ancient Greek philosopher Aristotle. who summed it up and whose message was so widespread. Aristotle said We become righteous. by doing righteous deeds. We become righteous by doing righteous deeds.

Or we become just by doing just acts. It was a self-help. Fake it till you make it message.

So, if you work at outward righteous act and keep doing them. it claimed, you will actually become a righteous person. And for years, Luther lived by the maxim, We become righteous by doing righteous deeds. As a monk, He desperately did all the righteous deeds he could imagine fasting, praying, pilgriming, monkery. And what he slowly came to realize Was the dream of becoming truly righteous?

By some Simple change. of behavior was just that. An elusive dream. Holding its reward ever just out of reach. It consistently promised righteousness without delivering it.

All the time exacting a heavier and heavier behavioral demand. In other words, by dangling the hope of becoming righteous. Before him, while repeatedly giving more deeds to do. That idea gradually enslaved him. Worse.

While doing all those outward acts of righteousness. He found It wasn't making him upright in heart. full of love for the Lord. quite the opposite as he's doing Ollie's Apparently, he thinks righteous acts. He found resentment snowballing inside him for.

The God who demands so many deeds, trying to sort himself out. And become righteous by his own efforts was driving him deep. Into slavery? despair And Hatred of God. Sim.

He began to see was not so easy a problem to whisk away. It went deep down in him. deeper down than he could reach himself. And so it was. In fifteen seventeen that Luther decided to challenge Aristotle.

And so A few weeks before posting his more famous ninety five theses, Luther posted his ninety seven Theses. And in them he wrote this. Hear how he's directly taking on Aristotle? Luther wrote, We do not become righteous by doing righteous deeds. Rather Having been made righteous, we do righteous deeds.

That is Our sin is not, he saw, something we can sort out by ourselves by adjusting our performance. If we are to be righteous, We have to be made. Rutches.

So how does that work?

Well Luther continues. He said The grace of God Makes righteousness abound through Jesus Christ. because it causes one to be Pleased. With the law. In other words, what we cannot do, the grace of God does.

A God in His kindness is able to reach down where we can't reach. Into our hearts and change not just the superficial layer of our behavior. but our very hearts. causing us to actually desire to be pleased with what is righteous. And that uprightness of heart is the only true uprightness.

Now, this is just where many would part ways with the Reformation. God Saving people. out of his sheer loving kindness.

Sounds wonderful. But people needing to be saved because they are otherwise helpless in their sin.

Sounds less pleasing. And we don't like hearing bad news. It was the same in Luther's day. In the early days of the Reformation, there were many who were vaguely sympathetic to the Reformation. They saw the need for some sort of change, some sort of reformation in the church.

They wanted the corruption, the mismanagement. Cleaned up. And they saw someone like Luther and thought, He's the new broom. who can come in. step up to the task and clean things up a bit.

And one such admirer was Erasmus. At the time, the most celebrated scholar in the world, the man who'd published the Greek New Testament that had converted Luther. Ariel? Erasmus' idea of Reformation was like his view of Christianity. He believed that what the Roman Catholic Church needed in his day.

was A few improvements. It was dirty and needed a wash. But nothing more radical or essential needed changing. And likewise with us all. Erasmus Feld.

He thought We could do better, we should do better, but That doesn't mean we're enslaved to sin. We just talked to Try a bit more. And so in fifteen twenty four Erasmus wrote On the freedom of the will. Arguing that sin is not something that affects us so deeply or powerfully that it actually enslaves us. Lusa saw this.

as an assault on the very vitals of the Reformation. and he responded with a blistering argument. on the bondage of the will.

Now the title that Luther gave his work written the next year. on the bondage of the will.

commonly throws people. For people's sake, I make free choices, don't I? Is Luther saying I can't do what I want? This idea of the bondage of the will, but that's a complete nonsense, they say. I do what I want every day.

My will seems very free, And actually Lisa would agree. We do always do what we want. But You do not. Choose What? to want.

For underneath our wills, directing and governing our choices. lie our hearts with their inclinations and desires. Proverbs 16, verse 9. In his heart. A man plans his course.

And that is why we choose to sin. We do not go through life neutrally weighing the odds of each decision. Should I go with the righteous option now or the sinful option? And then just sensibly choose between them neutrally. We choose sin because that's what we want.

We are carrying out Ephesians 2 the desires of the flesh. We naturally, John 3, love darkness. And so James one. Each person is tempted when he's lured and enticed by his own desire. And then desire, James writes, when it's conceived, gives birth to sin, and sin when it's fully grown brings forth death.

James 1, 14 and 15. What Luther had seen then? Is that the problem of our sin goes as deep in us as it possibly could. All the way down into our hearts. shaping What we want and love.

And as a result, we never naturally want God.

So we freely choose to do the things that we want, and that includes we have the ability to live a life of outward morality and respectability. We can do that. But left to ourselves, we will never choose God. Because we do not naturally want him.

Now Erasmus I've taken it that Our problem as sinners is Basically sloth. We are spiritually sluggish and sleepy. That's our problem. And what we need if we're to be righteous is pull ourselves together. Put in the proper effort.

Then you can do it. Luther's own experience had given the lie to all that. He left him saying, After years of monkery, I did not love, I hated the righteous God. I was angry with God. And with that in his heart, Luther had found he could strive as hard as he wanted.

And yet only find himself further than ever from actually fulfilling the law by loving the Lord his God. Loosen you. an outward appearance of righteousness he could achieve. But it be nothing more than a hollow sham. Made of self-dependence.

Self-worship. Self-righteousness. He saw. He was like a rotten tree producing rotten fruit. And sin was in his roots.

in the very grain of his deepest self, And what Luther needed. What he saw. All sinners need was a radical renewal. A new Heart. that would freely love and be pleased with God.

And that he saw would only come about through the love of God being spread abroad in our hearts by the Holy Spirit. He put it like this. The heart must be made glad. It must grow warm and melt in the love of God. And then.

Praise and thanksgiving will flow. From a pure heart. He's saying that it is when someone tastes the love, the grace, the glory of God through the gospel, then their eyes are opened. and their hearts are turned. And only then will they love God.

from a pure heart.

Now the difference Between Luther and Erasmus meant they ended up with two very different visions of Christianity. A superficial view of sin and a deep view of sin. ended in very different places. For Erasmus The church is most like an army. And one of his best-known works was entitled The Manual of the Christian Soldier.

And the important thing. He emphasized in that book for a Christian was. Keep the rules. Do your duty. like a good Christian soldier.

For Lucera, on the other hand. The church is first and foremost. Like a family. Knowing God the Father. is what matters above all.

And so, sin is not just substandard behavior, dereliction of duty, it's worse. Since is despising God. The act of sin has its roots in the heart. And reveals that something other than God has become the true object of the heart's desire and adoration. And when played out in real life, the difference between those two visions becomes very obvious.

See, if right behaviour is The goal. And if that's a goal that everyone can achieve. If they simply exert themselves properly, Well, then the church can run just like an army. Pastors can serve. There's the sergeant majors.

drilling their troops into line. Because after all, as Erasmus believed, Everyone is capable of getting into line. Why aren't the people more holy? because they're not trying hard enough. But if As Luther saw when made for a deeper class.

to love. to glorify, to enjoy God. And if we cannot naturally love him because we're enslaved to sin. then merely to order people to do what they can't is cruel. In other words, anyone who holds to Luther's deep view of sin must find their compassion swell and build.

Because people are not just naturally lazy. They are helpless. They need their very hearts. to be dealt with, not simply their performance. Above all.

They need the one thing with the power to turn and liberate their hearts. The Gospel. Luther asked. How shall a work? Please God, if it comes from a reluctant, resisting heart.

If hearts are enslaved To the charming lies of sin, if they're to be one to God. Then the glory of God in the face of Christ must be made known to them. Christ must be shown to be better. more desirable than sin. And that was how Luther would minister to people.

And so compare Erasmus' stern counsel of Trihada. With this from Luther. Luther wrote. I could not have faith in God if I did not think he wanted to be favorable and kind to me. This in turn makes me feel kindly disposed towards God.

And I'm Moved to trust him with all my heart and look to him for all good things. He goes on, look here. This is how you must cultivate Christ in yourself. Faith must spring up and flow from the blood, and wounds, and death of Christ. If you see in these God is so kindly disposed towards you, He even gives His Son.

for you. Then Your heart in turn will grow sweet and disposed towards God. He saw The cause sin. is a slavery. an addiction.

Luther saw he couldn't simply hector or order people out of it. That might bring about Such a bullying pastor could bring about behavioural change. You can enforce that somehow. But That will only reinforce a deeper self-dependence. No, ears need to be opened.

To the message of Christ and him crucified. Eyes need to be opened to the unfathomable kindness. And glory of the living God, and only in that gospel light. Can true humility Goodness. and charity grow.

You see, the Reformation's deep view of sin. goes all the way down into the hearts, enslaving us. It looks initially unattractive. But if sin is not much of a problem. Christ is not much of a Saviour.

And we don't need much grease. Only if I see. My plight is so bad I cannot fix it myself. Only then will I turn to Christ. And depend.

on him instead of myself. Only then will I despair of my efforts and look outside myself for hope. And that's what we see in the Gospels, isn't it? In the Gospels, it's the one with the great debt cancelled who loves most. In Luke 7, it's the forgiven prostitutes and tax collectors who weep with joy, give away their wealth, and love Jesus.

It's the Pharisees. Those who think they are something in themselves. I think they have something in themselves on which they can depend. It's them. They are the ones who never find that liberation.

That transformation. And historically too. Times of church reformation and revival have consistently been marked. a radical view of sin. It was on the lips of the preachers of the Great Awakening, men like George Whitfield, Jonathan Edwards.

as much as it was in the mouths of the reformers. For such men knew That calls for social improvement and better morality while good things. Do not touch the heart of the human condition. Corrupted all the way down. We cannot fix ourselves.

Our hearts must be renewed. And that can only happen. through the gospel being preached. and the glory of God being revealed. The Reformation's radical view of sin.

is why we sinners would throw ourselves on God's grace alone. A humbling and sobering message from Michael Reeves, reminding each of us that our hope is not found within ourselves.
