There is no regret in turning your life to God. The apostle Paul taught that Godly grief leads to repentance unto salvation without regret (2 Corinthians 7:10). Repentance has no regret. Repentance means to change one's mind to change one's life away from sins (Acts 26:20; Romans 12:1–2; Hebrews 6:1). Do you feel shame and guilt for sin? You will not regret repentance. Some experts confront guilt as "degradation" and work to eliminate guilt but not the sin. Again, repentance leads to salvation without regret.
            Christians should remain reflective of biblical teachings about repentance. Believers should be in a constant state of the renewing of the mind so that they do not conform to the world (Romans 12:1–2). If Christians are pleading to the world to repent, then the faithful must set the example of repenting. Paul taught, "The times of ignorance God overlooked, but now he commands all people everywhere to repent" (Acts 17:30 ESV). God wants all to come to repentance so they will be saved (2 Peter 3:9).

            When Paul confronted the church of Christ at Corinth for their sins, his teaching caused great sorrow. However, that sorrow was from God by which they repented of their sins. In recognition of this repentance, the apostle taught that his causing grief in others was so that they repent (2 Corinthians 7:8). Paul rejoiced for them not because they were grieved but because they repented (7:9). Repenting is not sorrow but the change that comes from the humility of Godly sorrow. Upon this, Paul noted, "For godly grief produces a repentance that leads to salvation without regret, whereas worldly grief produces death" (7:10). Godly grief produces earnestness to clear oneself of sin through a number of emotions of anger, fear, longing, and zeal (7:11). These reactions all revealed this church's earnestness to repent in the sight of God (7:12).
            How can Christians become more receptive of grief to repent? Believers can quit blaming others for their guilt and personal conflicts. How could someone make you feel guilty? "Don't make me feel guilty" is a strange response. Should you feel guilty for what you are doing? Maybe you should. If someone slandered you and framed you for murder, would you feel guilty for murdering someone? No. Someone cannot make you feel guilty if you did nothing wrong. Maybe I am wrong. Someone could make you doubt your choice of words as inconsiderate or even disrespectful. However, they are not making you feel guilty when you are innocent. Feeling guilty even for an unintentional action is your guilt, shame, and embarrassment that when this is Godly sorrow will help you change.

            Jesus revealed, "I have not come to call the righteous but sinners to repentance" (Luke 5:32). If you are not a sinner, why would you need Jesus? Christians must accept the saying, "Christ Jesus came into the world to save sinners, of whom I am the foremost" (1 Timothy 1:15). That is why Jesus taught, "No, I tell you; but unless you repent, you will all likewise perish" (Luke 13:3, 5). When Jesus resurrected from the dead, He taught, "that repentance for the forgiveness of sins should be proclaimed in his name to all nations, beginning from Jerusalem" (Luke 24:47; cf. Acts 20:21). Repentance leads to life (Acts 11:18). Repentance is essential to have one's sins forgiven through baptism in Jesus's name (Acts 2:38; 3:19; 10:43, 47–48).

            The faithful will repent unto salvation without regret. Jesus revealed, "Just so, I tell you, there will be more joy in heaven over one sinner who repents than over ninety-nine righteous persons who need no repentance" (Luke 15:7). Thank God for those who repent and bring about rejoicing in heaven.
