Understand that the penalty for your sin is death - eternal separation from God and all that is good. (Romans 6:23, Hebrews 9:27)
Believe that Jesus Christ took the penalty for your sin by dying in your place and conquered death by raising from the dead. (Romans 5:8, 2 Corinthians 5:21)
Receive the free gift of salvation by trusting in Christ alone as your Savior from sin and death and your provider of true and eternal life. (Romans 4:4-5, 5:1, Ephesians 2:8-9)
One way you can express your trust in Jesus Christ is by telling God Himself:
I know that I'm a sinner. I know my sin deserves to be punished. I believe Christ died for me and rose from the grave. I trust Jesus Christ alone as my Savior. Thank You for the forgiveness and everlasting life that I now have. It is because of Jesus that I have peace praying these things to you.
