The most important prayer is The Prayer for Salvation.
It isn't a particular prayer with exact words, but the prayer conveys that:
- you admit that you're a sinner
- you need Jesus to forgive you
- you believe that Jesus died on the cross to pay the penalty for your sins
- you want to accept Jesus as your Savior
- you want to follow Him as Lord of your life
A Sample Prayer
Dear Lord Jesus, I know that I am a sinner and need Your forgiveness. I believe that You died for my sins. I want to turn from my sins. I now invite You to come into my heart and life. I want to trust and follow You as Lord and Savior. In Jesus’ name. Amen.
