We all must know the sinner’s prayer because God has called everyone to be a soul winner.
While the sinner’s prayer isn’t exactly recorded in the Bible, the bottom line is to ask Jesus to forgive your sins and come into your heart and to promise to serve Him all the days of your life.
Salvation is accepting Christ and inviting Him into your heart. You can know all about Jesus and still not know Him
There are three passages in Romans that lead the way to salvation.
Romans 3:23: “For all have sinned and fall short of the glory of God.”
Romans 6:23: “For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.”
Romans 10:9-10: “That if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation.”
