The Biblical commandment to repent:

“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

“He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.” – Proverbs 28:13

“And saying, Repent ye: for the kingdom of heaven is at hand.” – Matthew 3:2

“And Jesus answering said unto them, They that are whole need not a physician; but they that are sick. I came not to call the righteous, but sinners to repentance.” – Matthew 5:32-33

“³ I tell you, Nay: but, except ye repent, ye shall all likewise perish.⁴ Or those eighteen, upon whom the tower in Siloam fell, and slew them, think ye that they were sinners above all men that dwelt in Jerusalem?⁵ I tell you, Nay: but, except ye repent, ye shall all likewise perish.” – Luke 13:3-5

“8 Draw nigh to God, and he will draw nigh to you. Cleanse [your] hands, [ye] sinners; and purify [your] hearts, [ye] double minded.9 Be afflicted, and mourn, and weep: let your laughter be turned to mourning, and [your] joy to heaviness.10 Humble yourselves in the sight of the Lord, and he shall lift you up.” – James 4:8-10

“But after thy hardness and impenitent heart treasurest up unto thyself wrath against the day of wrath and revelation of the righteous judgment of God;” – Romans 5:2

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.” – Acts 3:19

“When they heard these things, they held their peace, and glorified God, saying, Then hath God also to the Gentiles granted repentance unto life.” – Acts 11:18

“And the times of this ignorance God winked at; but now commandeth all men every where to repent:” – Acts 17:30

If you don’t know Jesus Christ as your Lord and Savior, you can receive Him into your heart, and He can deliver you from darkness and sin and have your name written in His Book of Life.

If you are sincere, you can say this simple prayer to the Father (it doesn’t have to be word for word):

“God, I recognize that I have not lived my life for You up until now. I have been living for myself and that is wrong. Please forgive me of all of my sins, just as I forgive others. I need You in my life; I want You in my life. I acknowledge the completed work of Your only-begotten Son Jesus Christ in giving His life for me on the cross, I believe in my heart Jesus is Lord and was raised from the dead and I long to receive the forgiveness you have made freely available to me through this sacrifice. Come into my life now, Lord. Take up residence in my heart and be my king, my Lord, and my Savior. From this day forward, I will no longer be controlled by sin, or the desire to please myself, but I will follow You all the days of my life. Those days are in Your hands. I ask this in the Lord and GOD Jesus’ precious and holy name. Amen.”
