Genesis 6:6 KJV
And it repented the Lord that he had made man on the earth, and it grieved him at his heart
The Lord repented for making mankind on earth and it caused the Good Lord to be grieved. This does not mean that God admits a mistake or sin, but it means it condescends to us through human language so we might understand that mankind has sinned in His awesome, omnipresent presence.
Genesis 6:7 KJV
And the Lord said, I will destroy man
whom I have created from the face of the earth; both man, and beast, and
the creeping thing, and the fowls of the air; for it repenteth me that I have made them.
Again, God repents in making man because He uses anthropomorphic language so we understand that man has committed serious wickedness and he must reform by God's divine grace.
Exodus 13:17 KJV
And it came to pass, when Pharaoh had let the people go, that God led
them not through the way of the land of the Philistines, although that
was near; for God said, Lest peradventure the people repent when they see war, and they return to Egypt:
Exodus 32:12 KJV
Wherefore should the Egyptians speak, and say, For mischief did he bring
them out, to slay them in the mountains, and to consume them from the
face of the earth? Turn from thy fierce wrath, and repent of this evil against thy people.
Repentance should only be used for good purposes unto God's glory. We ought to never repent of right things that we do, but it does not mean that those good deeds are not stained with corruption and also need forgiveness and cleansing. God promises that through His Son He is able to take away our sin.
Exodus 32:14 KJV
And the Lord repented of the evil which he thought to do unto his people.
Here the Lord repents again: it never means He made a mistake or sin but He sometimes relents of His justice and stops His progression of His indignation against His people.
Numbers 23:19 KJV
God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?
God never repents of sin, but He repents to turn the people onto justice or to remove justice from them.
Deuteronomy 32:36 KJV
For the Lord shall judge his people, and repent himself for his servants, when he seeth that their power is gone, and there is none shut up, or left.
The Lord has mercy on His people.
Judges 2:18 KJV
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.
The Lord repents and removes His justice against the people.
Judges 21:6 KJV
And the children of Israel repented them for Benjamin their brother, and said, There is one tribe cut off from Israel this day.
Judges 21:15 KJV
And the people repented them for Benjamin, because that the Lord had made a breach in the tribes of Israel.
We ought to never stop repenting. Death ends repentance, but everyone who repents seeks to be pleasing to God and also do works of repentance to honor God in small or great ways.
1 Samuel 15:11 KJV
It repenteth me that I have set up Saul to be king: for he is
turned back from following me, and hath not performed my commandments.
And it grieved Samuel; and he cried unto the Lord all night.
Again the Lord puts it into our understanding: He regrets that He made Saul king.
1 Samuel 15:29 KJV
And also the Strength of Israel will not lie nor repent: for he is not a man, that he should repent.
The Lord never sins nor makes a mistake. He only repents to teach us about what He is doing and He puts it into our language so we comprehend His divine message.
1 Samuel 15:35 KJV
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.
The Lord puts it into human language: Saul should not have been made king but it was judgment upon the people of God because they sinned in wanting a king.
2 Samuel 24:16 KJV
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.
We ought to remember mercy in judgment.
1 Kings 8:47 KJV
Yet if they shall bethink themselves in the land whither they were carried captives, and repent,
and make supplication unto thee in the land of them that carried them
captives, saying, We have sinned, and have done perversely, we have
committed wickedness;
We ought to always remember our sin before God and acknowledge our sin before God and man and His angels. We ought to confess our sin to the Lord and He is faithful to forgive.
1 Chronicles 21:15 KJV
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.
The Lord stops the judgment because He remembers mercy in His judgments.
Job 42:6 KJV
Wherefore I abhor myself, and repent in dust and ashes.
We all should be like Job and repent in dust and ashes. Job was a family man and he served God with all his heart and loved his neighbor as himself. Job was a sinner but he repent because the Spirit granted it to him. We ought to pray that the Spirit grants us repentance and faith to please God.
Psalm 90:13 KJV
Return, O Lord, how long? and let it repent thee concerning thy servants.
He never changes His mind but it only means if we repent He changes His course of judgment upon His slaves.
Psalm 106:45 KJV
And he remembered for them his covenant, and repented according to the multitude of his mercies.
The Lord is always faithful and He has mercy on the disobedient and evildoers.
Psalm 110:4 KJV
The Lord hath sworn, and will not repent, Thou art a priest for ever after the order of Melchizedek.
The Lord made Jesus a High Priest forever after the order of Melchizedek. He does not decide to change it but keeps it forever under His divine vow.
Psalm 135:14 KJV
For the Lord will judge his people, and he will repent himself concerning his servants.
The Lord searches our hearts and minds; that is, Jesus is a Master of this and God favors His slaves who work His will wheresoever they go.
Jeremiah 4:28 KJV
For this shall the earth mourn, and the heavens above be black; because I have spoken it, I have purposed it, and will not repent, neither will I turn back from it.
God will not turn from His anger nor will He repent nor decide against it. We ought to fear God's corrective judgment and chastening so we do not sin again.
Jeremiah 8:6 KJV
I hearkened and heard, but they spake not aright: no man repented him of his wickedness, saying, What have I done? every one turned to his course, as the horse rusheth into the battle.
We ought to always repent when we have done wrong. The Spirit grants us repentance through His goodness of lovingkindnesses. We ought to ask what we have done and how we have sinned. True forgiveness is the importation of the application of Jesus' merits by His Holy Spirit.
Jeremiah 15:6 KJV
Thou hast forsaken me, saith the Lord, thou art gone backward: therefore will I stretch out my hand against thee, and destroy thee; I am weary with repenting.
We ought to never forsake the Lord. We ought to repent and bear deeds of repentance. The Lord is faithful and He will see us through.
Jeremiah 18:8 KJV
If that nation, against whom I have pronounced, turn from their evil, I will repent of the evil that I thought to do unto them.
It means He takes away the judgement and puts His purpose in the sense of our language.
