Charles Spurgeon Commentary Jeremiah 3:5

"Will he retain [his anger] for ever? will he keep it to the end? Behold, thou hast spoken and hast done evil things, and hast had thy way." — Jeremiah 3:5 (ASV)

Will he reserve his anger for ever? Will he keep it to the end?

No, that he will not; no one is so slow to anger as our God, and no one is so ready to be rid of it as he is. He is a God ready to pardon, waiting to forgive, delighting in mercy. Even though the sin may be so foul that, as I read it to you, I seem almost to blush in the reading, as you may in the hearing, yet, black as it is, God can put it all away in the greatness of his mercy.

Behold, thou hast spoken and done evil things as thou couldest.

You have gone as far in sin as you could go; only lack of power has prevented you from being even worse than you are. Yet this is the kind of people to whom God speaks in mercy, inviting them to return to him.
