If you want to accept Jesus’s offer of forgiveness and eternal life, you only need to say a simple prayer (out loud or just in your head). If you say this prayer to Him, I can guarantee He will come into your heart and change you for the better.
I accept that I am a sinner and need your forgiveness. I believe you came into this world to die for me, so that I can have eternal life. I believe you rose from the dead and are now alive in heaven with God, your father. Please come into my heart and be my Lord and Saviour. Please help me to live in the way you want me to.
