God wants to save everyone. He loves us so much that He gave his Son to die for our sins. Our sins are forgiven when we are baptized into Christ, and God promises us the gift of eternal Life. Nowhere in the New Testament is anyone told to pray to receive salvation and become a Christian. God is gracious and merciful, not willing that any should perish, but that all should come to repentance (2 Pet 3:9). Repentance was preached by Jesus Christ (Matthew 4:17), by John the Baptist (Matthew 3:1-10), by Christ’s Disciples (Mark 6:12), by Peter (Acts 2:38), by Paul (Acts 17:30), the gospel, calls for “repentance toward God…” (Acts 20:21).
Those who truly repent change their mind about their relationship with God and this results in a change in the way they live. Judas regretted his actions, but he did not turn to God(Matt. 27:3-4)There are lots of preachers who made repentance a simple .
The truth is that the Bible teaches that baptism is when our sins are washed away and we are forgiven unto salvation not through sinner’s prayer. There is no way an unsaved sinner can ask and receive salvation through prayer, because an unsaved sinner is not "in Christ" he is out of Christ the Bible clearly teaches that the only way to get "in Christ" is to be "baptized into Christ. (Mark 16:16, Acts 2:38, 1 Peter 3:21 )
Someone may have prayed this prayer during an emotional experience and then go on living their life as they were before. This person has a false assurance of salvation.
Saul of Tarsus prayed for three days after arriving in the city of Damascus, yet his sins were not “washed away” until he was immersed in water in obedience to the divine command (Acts 9:11; 22:16). Jesus nor any of the apostles ever taught or wrote that we must pray a sinners prayer to be saved. God only hears those who worship Him and do His will. Example when the multitudes cried out at Pentecost, “What shall we do?” Peter did not respond, “Pray the sinner’s prayer,” but “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 2:37-38). A Christian is one who belongs to Christ and obeys His commands (1 John 5:3). When a person does exactly what the Bible teaches in order to be saved and lives a faithful life on earth, eternal life in heaven awaits them (Revelation 2:10).
We see in many Bible verses that God rejected sinner’s prayer. Below are the examples.
