Lamentations 3:21–23

“The steadfast love of the LORD never ceases; his mercies never come to an end; they are new every morning; great is your faithfulness.”

We know what it is like to be disappointed by someone who did not keep their word. Sometimes people forget. Sometimes circumstances change. Sometimes promises are made sincerely but prove impossible to keep. And sometimes people simply prove untrustworthy.

Our experience with one another can make trust difficult. But God is not like us.

He never forgets. He never lies. He never makes a promise only to discover that circumstances have made it impossible to fulfill. He never changes His character or abandons His purposes. The Lord is perfectly faithful to Himself, His Word, and His people. Therefore, we can trust Him completely in every circumstance.

Jeremiah understood how precious that truth becomes when life is painful.

Faithfulness in the Darkness

The familiar words “great is your faithfulness” were not written during a season of comfort and prosperity.

Jeremiah spoke them while grieving the destruction of Jerusalem. God's judgment had fallen through the Babylonian invasion. The city was devastated, its people were suffering, and Jeremiah was surrounded by reasons for despair. Yet in the darkness he deliberately called something to mind:

“The steadfast love of the LORD never ceases; his mercies never come to an end” (Lamentations 3:22).

Jeremiah's circumstances had changed dramatically. God had not.

That is what makes God's faithfulness such a powerful anchor for suffering believers. Our hope does not ultimately rest upon our ability to understand what God is doing. It rests upon the unchanging character of the One who is doing it.

God's faithfulness means that He will always be true to who He is. “If we are faithless, he remains faithful—for he cannot deny himself” (2 Timothy 2:13).

He will never become less holy, less loving, less wise, or less good. Nothing outside of God can alter His character. Human failure cannot make Him unfaithful.

When everything around us seems uncertain, God remains exactly who He has always been.

Not One Word Will Fail

Because God is faithful to Himself, He is also faithful to His Word.

Scripture says that it is impossible for God to lie (Hebrews 6:18). His promises are not expressions of good intentions about what He hopes to accomplish. They are declarations from the sovereign God concerning what He has committed Himself to do.

Joshua could therefore look back upon God's dealings with Israel and say, “Not one word of all the good promises that the LORD had made to the house of Israel had failed; all came to pass” (Joshua 21:45).

That does not mean God's promises are always fulfilled according to our preferred timetable.

Abraham waited approximately twenty-five years for the promised son. Joseph endured slavery and imprisonment before seeing God's purposes unfold. Israel waited generations for the promised Messiah. And the church continues to wait for Christ's return.

Waiting does not mean God has forgotten. Hebrews 10:23 tells us to “hold fast the confession of our hope without wavering, for he who promised is faithful.”

Our circumstances change constantly. God's promises do not.

So when His timing differs from ours, we must resist the temptation to take matters into our own hands. We continue believing, praying, and obeying. Delay is not evidence of divine unfaithfulness. The God who made the promise knows precisely when and how it should be fulfilled.

Every Promise Finds Its Yes in Christ

The history of Scripture is the history of God's covenant faithfulness.

He made promises to Noah, Abraham, Israel, and David. Generations came and went. God's people repeatedly failed. Yet their unfaithfulness could not overturn God's purposes.

“What if some were unfaithful?” Paul asks. “Does their faithlessness nullify the faithfulness of God? By no means!” (Romans 3:3–4).

And eventually, all those promises converged upon one Person.

Jesus is the promised offspring of Abraham, the promised Son of David, Israel's Messiah, and the Mediator of the new covenant. “All the promises of God find their Yes in him” (2 Corinthians 1:20).

If we ever wonder whether God keeps His Word, we should look to Christ.

Look at Bethlehem: God kept His promise.

Look at Calvary: God kept His promise.

Look at the empty tomb: God kept His promise.

And look toward the return of Christ, when the One Revelation calls “Faithful and True” will come again and fulfill every promise that remains (Revelation 19:11).

The cross especially assures us that God's faithfulness does not depend upon our worthiness. Christ died for sinners. The new covenant rests upon His finished work, not our flawless performance. The God who began His saving work in His people will bring it to completion.

Faithful in Every Circumstance

God does not intend His faithfulness to remain an abstract doctrine. He gives us promises so that we will actually trust Him in the circumstances of everyday life.

When temptation comes, God is faithful to provide what is necessary to endure it (1 Corinthians 10:13).

When we confess our sins, God is faithful to forgive us because Christ has paid the penalty (1 John 1:9).

When suffering comes, we can entrust ourselves to our “faithful Creator” while continuing to do good (1 Peter 4:19).

When we are weak and struggling to grow, Scripture says, “He who calls you is faithful; he will surely do it” (1 Thessalonians 5:24).

And when we wonder whether we will persevere to the end, we remember that our salvation ultimately rests upon God's keeping power. He is able to present His people blameless before His glory with great joy (Jude 24).

Faithfulness does not mean God promises to spare us from every painful circumstance. Jeremiah knew better than that. Sometimes God's faithfulness carries us through suffering rather than removing it.

But suffering cannot make Him abandon us. Waiting cannot make Him forget us. Our weakness cannot exhaust Him. And nothing in heaven or earth can prevent Him from fulfilling what He has promised.

Perhaps that is why “great is your faithfulness” shines so brightly from the darkness of Lamentations. Jeremiah did not deny what was happening around him. He simply refused to allow his circumstances to have the final word about God's character.

We can do the same.

When everything else feels uncertain, call this to mind: God has not changed. Christ has not failed. His Word remains true. His mercies are still new every morning.

And tomorrow, He will still be faithful.
