He will not always accuse; neither will he stay angry forever. — Psalms 103:9
For our light affliction, which is for the moment, works for us more and more exceedingly an eternal weight of glory. — 2 Corinthians 4:17

Summary: God rebukes His children when they stray, and that rebuke is especially painful when we recognize that we deserve it and regret having grieved Him. But His contention does not last forever. If we repent and return to Him with hearts broken over sin, He receives us with love and restores our joy. Therefore, we can seek His face without despairing or giving in to discouragement. The God who forgave us as Judge can forgive us again as Father; His love remains unchanged.
He will contend at times, for He would not be a wise father to such poor, wandering children as we are if He did not. His rebuke is very painful to those who are sincere, for they feel how sadly they deserve it and how wrong it is of them to grieve Him. We know what this contention means, and we bow before the Lord, lamenting that we have led Him to be angry with us.
But what comfort we find in these lines! He will not contend “forever.” If we repent and return to Him with hearts broken over sin and broken by its consequences, He will smile upon us at once. He takes no pleasure in turning a frowning face toward those He loves with all His heart: He delights in our joy being full.
Come, let us seek His face. There is no reason for despair, or even for discouragement. Let us love the God who contends, and before long we will sing: “Your anger has turned away, and You have comforted me.” Away with you, dark forebodings, ravens of the soul! Come to me, humble hopes and grateful memories, doves of the heart! He who forgave us long ago as a judge can forgive us again as a Father, and we will rejoice in His sweet, unchanging love.
