When the Bible tells humans to 'repent', it is about our having to stop doing our sins.
Way back in 1 Kings 8:47 and if they have a change of heart in the land where they are held captive, and repent and plead with you in the land of their captors and say, ‘We have sinned, we have done wrong, we have acted wickedly’;
That is about REPENTING OF SINS.
You say we are only to have a change of heart about God. God says we are to have a change of heart about SIN.
2 Chronicles 6:37 and if they have a change of heart in the land where they are held captive, and repent and plead with you in the land of their captivity and say, ‘We have sinned, we have done wrong and acted wickedly’;
Job 34:33 Should God then reward you on your terms, when you refuse to repent? You must decide, not I; so tell me what you know.
What does Job say?
He says to REPENT of evilness.
Proverbs 1:23 Repent at my rebuke! Then I will pour out my thoughts to you, I will make known to you my teachings.
That scripture proves God gives understanding to those who obey.
Here, this scripture is going to explain it to you in the simplest form yet.
Isaiah 59:20 “The Redeemer will come to Zion, to those in Jacob who repent of their sins,” declares the Lord.
Repent of their what?
Repent of their wickedness!
Jeremiah 8:6 I have listened attentively, but they do not say what is right. None of them repent of their wickedness, saying, “What have I done?” Each pursues their own course like a horse charging into battle.
