Giving your life to Jesus changes everything. Jesus came to reveal who God is and to restore our relationship with Him. No matter your past mistakes or your present fears, Jesus can give you a new life in Him. All you need to do is put your faith in Him.
The Bible says this in Romans 10:9, "If you declare with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved."
It is a turning from our old ways and turning to Jesus, to ask Him for forgiveness from our sins and to give us new life in Him.
You can say a simple prayer like this just be sure to mean it from your heart.
"God, I know that I have sinned. I am reaching out to you because I want forgiveness. I believe that His death and resurrection provided for my forgiveness. I trust in Jesus and Jesus alone as my personal Lord and Savior. Thank you Lord, for saving me and forgiving me! Amen!"
