CLIP: An URGENT Plea With Unbelievers (Isaiah 55)

Jim Butler · 2025-05-04 · Isaiah 55 · 631 words · 4 min

Summary

Expository

Unbelievers must urgently seek the Lord while he may be found, for the window of saving grace will close, yet God abundantly pardons every sinner who returns to him through Christ.

Isaiah 55 issues an urgent, time-sensitive call to unbelievers: the window of grace will close, and those who die outside of Christ will face the wrath of a thrice-holy God. The sermon confronts common self-excuses for delaying repentance — including the notion that one's sins are too great — and answers them with the inexhaustible pardoning grace of God. Every sinner is summoned to seek the Lord while he may be found, flee to Christ immediately, and rest in the abundance of his mercy.

Key quotes

Because you're so sinful, you should flee immediately to Jesus.
I've got an abundance of sins, Jesus has an abundance of grace.
Newton said, I'm a great sinner, but I have a great Savior. And everyone in here, in Christ, can testify to the same.

Applications

  1. Unbelievers, seek the Lord now while he may be found — do not presume upon a future opportunity that may never come.
  2. Do not use the greatness of your sin as a reason to delay coming to Christ; rather, let it be the very reason you flee to him immediately.
  3. Call upon the Lord while he is near, forsake your wicked way and unrighteous thoughts, and return to God who will abundantly pardon.
  4. Believers, testify with Newton: 'I am a great sinner, but I have a great Savior.'

Questions this sermon answers

What is the main problem facing every unbeliever?

The speaker says the sinner's problem is not a lack of personal adjustment but sin against a thrice-holy God, which brings his wrath, fury, and the judgment of eternal damnation.

Is there a deadline for responding to the gospel?

Yes — Isaiah 55:6 commands people to seek the Lord 'while he may be found,' implying a time is coming when the door will close and it will be too late to respond.

What if my sins are too great for God to forgive?

The speaker argues that the abundance of sin is no barrier, because God abundantly pardons; an abundance of sins should drive the sinner to flee immediately to Jesus, not to stay away.

What does the Bible say hell is actually like?

The speaker describes it as a place of misery, suffering, pain, weeping, wailing, and gnashing of teeth — not, as some flippantly suggest, a place where one could simply take over.

Urgent Call to Unbelievers

Again, taking into consideration the entirety of the chapter, it's a bit of an exhortation to believers and unbelievers. Unbelievers, you should listen to what the prophet says and come to the Savior. I don't know how to make that clearer or plainer. If I knew 20 languages, I would say it in 20 languages.

You need to listen to the prophet Isaiah. You've got problems, and your problem isn't, well, I'm just not as well adjusted as everybody else. No, your problem is, you sin against a thrice holy God. Your problem is, is eternal damnation as a result of that sin against a thrice holy God.

Your problem is, is that if you die tonight, or you die today, or you died right now, you drop into hell. The problem is the wrath and fury and judgment of the Most High God. His eye is too pure to look approvingly upon any evil. The prophet tells us that.

The psalmist tells us that God is angry with the wicked every day. There's even an urgency in our own chapter.

The Window of Grace Will Close

Notice in Isaiah 55 verse 6, seek the Lord, notice, while he may be found. What does that imply? There's a time coming when he won't be found. There's a time coming when it will be too late.

There's a time coming when you may knock and there will be no answer. So there's an urgency on the part of the prophet. There's an urgency on the part of the entirety of Scripture. Now is the acceptable time.

Today is the day of salvation. So unbeliever, listen to what the prophet says. Seek the Lord while he may be found. Call upon him while he is near.

Let the wicked forsake his way and the unrighteous man his thoughts. Let him return to the Lord. And you have this blessed assurance. He will have mercy on him and to our God, for he will abundantly pardon.

So if you're sitting there right now saying, well, I am a sinner. I am an unbeliever. I haven't looked to the Lord Jesus Christ. But man, I'm quite the sinner.

Jesus is quite the Savior. I've got an abundance of sins, Jesus has an abundance of grace. In him, we have redemption through his blood, the forgiveness of sins according to the riches of his grace, Ephesians 1.7.

Abundance of Sin, Abundance of Grace

So don't try to talk yourself out of coming to Jesus because you're so sinful. Because you're so sinful, you should flee immediately to Jesus. That's my encouragement to any unbelievers. Whether you're old, whether you're young, whether you're a man or whether you're a woman, it doesn't matter.

You've sinned against a thrice holy God. Undealt with sin deserves God's wrath and curse both in this life and that which is to come. If you do not believe, if you do not repent, you will die in your sins. And the Bible describes for us in vivid detail what that looks like.

It's not a walk in the park. It's not like some fools out there say, well, heaven doesn't want me and hell's afraid I'm going to take over. Take over suffering? Take over pain?

Take over weeping and gnashing of teeth? Really, that's what you want to go with that? Well, I'd rather go to hell because all my friends are going to be there. Yeah, what a party that's going to be.

Misery, suffering, pain, weeping, wailing, gnashing of teeth. So brethren, or unbelievers, listen to the text. Seek the Lord while He may be found. Call upon Him while He is near.

Why? Because He abundantly pardons. Newton said, I'm a great sinner, but I have a great Savior. And everyone in here, in Christ, can testify to the same.
