Well, that is the
modern interpretation of the word repent, but not what it meant years ago, just as the word "replenish" in Gen 1:28 and Gen 9:1 meant "to fill" the earth, but now has come to mean "refill". God's Word has not changed, but the English language has.
If repent means to be sorry
for sin, then God is a sinner.
Gen 6:6 And it
repented the LORD that he had made man on the earth, and it grieved him at his heart.
Exo 32:14 And the LORD
repented of the evil which he thought to do unto his people.
Judges 2:18 And when the LORD raised them up judges, then the LORD was with the judge, and delivered them out of the hand of their enemies all the days of the judge: for it
repented the LORD because of their groanings by reason of them that oppressed them and vexed them.
1 Sam 15:35 And Samuel came no more to see Saul until the day of his death: nevertheless Samuel mourned for Saul: and the LORD
repented that he had made Saul king over Israel.
2 Sam 24:16 And when the angel stretched out his hand upon Jerusalem to destroy it, the LORD
repented him of the evil, and said to the angel that destroyed the people, It is enough: stay now thine hand. And the angel of the LORD was by the threshingplace of Araunah the Jebusite.
1 Chron 21:15 And God sent an angel unto Jerusalem to destroy it: and as he was destroying, the LORD beheld, and he
repented him of the evil, and said to the angel that destroyed, It is enough, stay now thine hand. And the angel of the LORD stood by the threshingfloor of Ornan the Jebusite.
Psa 106:45 And he remembered for them his covenant, and
repented according to the multitude of his mercies.
Jer 26:19 Did Hezekiah king of Judah and all Judah put him at all to death? did he not fear the LORD, and besought the LORD, and the LORD
repented him of the evil which he had pronounced against them? Thus might we procure great evil against our souls.
Amos 7:3 The LORD
repented for this: It shall not be, saith the LORD.
Amos 7:6 The LORD
repented for this: This also shall not be, saith the Lord GOD.
God cannot sin, so repented cannot mean to turn
from sin.
Here is an article about repentance from Curtis Hutson that is pretty good.
