All you have to do is ask...

"God, I know I've disobeyed you, and I'm sorry for what I've done. I know I'm a sinner in need of a Savior and only Jesus can save me. God, please forgive me and give me eternal life. Thank you, Jesus for dying for me. From this day forward, as an expression of my love for you, I will make a sincere effort to follow you, allowing your teachings to shape the way I think and act.   Amen."
