Here is a sample prayer to express repentance and trust in Jesus Christ for salvation.
Note: Only God can save you, and he will upon your repentance and trust in Jesus Christ for salvation.
“God, I am a sinner, unable to become righteous in myself. However, I believe that you died on a cross for us, and rose from the dead 3 days later. I repent of all my sins against you, and trust you wholeheartedly to save me. Thank you for giving me eternal life with you, and making me a new creation. Amen!”
