It is written:
From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand.
Matthew 4:17
And again it is written:
Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
Acts. 2:38
and again it is written:
Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord. And he shall send Jesus Christ, which before was preached unto you. Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began.
Acts 3:19-21
and it is written:
Now I rejoice, not that ye were made sorry, but that ye sorrowed to repentance: for ye were made sorry after a godly manner, that ye might receive damage by us in nothing. For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death. For behold this selfsame thing, that ye sorrowed after a godly sort, what carefulness it wrought in you, yea, what clearing of yourselves, yea, what indignation, yea, what fear, yea, what vehement desire, yea, what zeal, yea, what revenge! In all things ye have approved yourselves to be clear in this matter.
2 Corinthians 7:9-11

If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land.
2 Chronicles 7:14
and it is written:
If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
1 John 1:9
and it is written:
I tell you, Nay: but, except ye repent, ye shall all likewise perish.
Luke 13:3
and it is written:
But if the wicked will turn from all his sins that he hath committed, and keep all my statutes, and do that which is lawful and right, he shall surely live, he shall not die. All his transgressions that he hath committed, they shall not be mentioned unto him: in his righteousness that he hath done he shall live. Have I any pleasure at all that the wicked should die? saith the Lord God: and not that he should return from his ways, and live?
Ezekiel 18:21-23
and it is written:
And the times of this ignorance God winked at; but now commandeth all men every where to repent:
Acts 17:30
and it is written:
Draw nigh to God, and he will draw nigh to you. Cleanse your hands, ye sinners; and purify your hearts, ye double minded. Be afflicted, and mourn, and weep: let your laughter be turned to mourning, and your joy to heaviness. Humble yourselves in the sight of the Lord, and he shall lift you up.
James 4:8-10
and it is written:
He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.
Proverbs 28:13
