The God Who Keeps His Word

At the end of the book of Joshua there is a sentence that I believe deserves to be underlined in every Bible. After all the battles, all the waiting, all the long years between the promise and its fulfillment, the writer pauses to take stock and says this: "Not one of all the Lord's good promises to Israel failed; every one was fulfilled." Read that slowly. Not one failed. Every one fulfilled. That is the verdict of history on the faithfulness of God.

Now consider how long Israel had waited for those words to be true. The promise to give Abraham's descendants a land had been spoken centuries earlier, to an old man with no children. Between the promise and this sentence lay generations of delay — slavery in Egypt, the long night of bondage, the wilderness years, the wandering, the doubting, the fear. There were surely many moments when the promise seemed dead. And yet, looking back across the whole sweep of it, the verdict stands: not one good promise of God fell to the ground. Every single one came true, in its time.

This is the heart of what I want to teach you about the Word of God. The Bible is not, at its core, a book of rules, though it contains commands. It is not merely a book of wisdom, though it is full of wisdom. The Bible is, above all, the record of a promise-keeping God. From Genesis to Revelation it tells one great story: God speaks, and God does what He says. He is the God who keeps His word.

I want you to grasp why this matters so deeply for your own faith. Your whole Christian life rests on promises you have not yet seen fulfilled. You have been promised that God will never leave you, yet there are days you feel utterly alone. You have been promised that He works all things together for good, yet you are in the middle of a season where you cannot see a single good thing. You have been promised a resurrection and a home with Him forever, yet you stand at the graveside of someone you love and the promise feels very far away. In every one of these moments, your peace will depend on one question: can I trust the One who made the promise?

And here is where the long story of Scripture becomes such a comfort. We are not asked to trust a God with no track record. We are asked to trust the God of Joshua 21:45 — the God whose promises, across thousands of years and countless impossible situations, have never once failed. When the sea stood as a wall and Israel walked through on dry ground, He was keeping His word. When the walls of Jericho fell, He was keeping His word. When a virgin conceived and a Savior was born in Bethlehem exactly as the prophets foretold, He was keeping His word. And when that Savior rose from the dead on the third day, just as He had said, the God who keeps His word gave the greatest proof the world has ever seen. The empty tomb is God's signature on every promise He has ever made.

So when you open your Bible, I want you to read it as the living word of a faithful God, not as ancient advice. There is a difference between reading the promises of God as nice sentiments and receiving them as the sworn word of the One who cannot lie. The same God who spoke to Abraham, who led Israel into the land, who raised Jesus from the dead — that God is speaking to you through these pages. And His character has not changed. He is not less faithful to you than He was to them.

Let me give you some counsel for how to live in light of this. First, learn the promises. You cannot lean on what you do not know. Many of God's people are anxious not because the promises are weak but because they have never taken the time to learn them. Second, hold the promises through the delay. Remember that between the promise and its fulfillment there is almost always a waiting. The delay is not a sign that God has forgotten; it is the very arena in which faith grows. Third, look back and build your faith. When your faith for the future grows weak, look at the past — both the long faithfulness of God in Scripture and the particular faithfulness of God in your own life. A remembered mercy is fuel for present trust.

I am an old man now, and I can add my own small testimony to the witness of Scripture. Across all the years of my life and ministry, through trials I would not have chosen and valleys I did not understand, I can say with the writer of Joshua: not one of God's good promises to me has failed. He has been faithful every single time. And the God who has kept His word to me, and to all His people through every age, will keep His word to you. You can stake your life on it. Many of us already have.
