I believe the Bible never, ever contradicts itself. God does not ever regret.
Numbers 23:19
" God is not a man, that He should lie; neither the son of man, that He should repent: hath he said and shall not do it? Or hath He spoken, and shall he not make it good?"
Now, this is God! He does not repent or regret. What he says goes.
Genesis 6:6
"And it repented the Lord that He had made man on the earth, and it grieved Him at His heart."
Can somebody explain to me these verses. Can God regret?
