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.


Repentance is one of the first principles of the gospel and is essential to our temporal and eternal happiness. It is much more than just acknowledging wrongdoings. We are all born with a sin nature that leads us constantly away from God (Ephesians 2:1-2). Left to ourselves, we will always walk in the wrong direction. A survey of the New Testament shows that the words “repent” and “repentance” are used in various forms 55 times. John the Baptist cried out, “Repent, for the kingdom of heaven is near” (Matthew 3:2). The entire message of Jesus is summed up in these words: “Repent and believe the good news” (Mark 1:15).

“And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel.”
Biblically, to become a Christian, one must repent and believe; a believer in Christ is one who has repented of sin. What, then, of professed believers who live in unrepentant sin? Most likely, they are not saved; they are mere professors, with no work of the Holy Spirit in their hearts. The apostle John states it bluntly: “If we claim to have fellowship with him and yet walk in the darkness, we lie and do not live out the truth” (1 John 1:6). The other possibility is that people claiming to be saved yet living in unrepentant sin are saved but acting in disobedience—in which case their unrepentance is a temporary hardness of heart, and God will discipline them (Hebrews 12:4–13). There is a sin unto death for the believer (1 John 5:16; cf. 1 Corinthians 11:29–31), but, barring that extreme circumstance, God will eventually restore His disobedient child to fellowship.

(see 1 Corinthians 5:1–5).

It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father’s wife. 2.  And ye are puffed up, and have not rather mourned, that he that hath done this deed might be taken away from among you. 3. For I verily, as absent in body, but present in spirit, have judged already, as though I were present, concerning him that hath so done this deed, 4. In the name of our Lord Jesus Christ, when ye are gathered together, and my spirit, with the power of our Lord Jesus Christ, 5. To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus.

(1 Corinthians 5:1–5).

Through the Atonement of Jesus Christ, our Father in Heaven has provided the only way for us to be forgiven of our sins (see Forgiveness). Jesus Christ suffered the penalty for our sins so we can be forgiven if we sincerely repent. As we repent and rely on His saving grace, we will be cleansed from sin
