Say the following prayers and mean it with all your heart:
O Lord God, I come to You in the name of Jesus. I believe that Jesus Christ is Your Son. I believe that You raised Him from the dead and I confess with my mouth that Jesus Christ is the Lord of my life from today. I receive by faith, remission of sins for my soul, and right now, in the Name of Jesus Christ, I receive eternal life into my spirit. I declare with my mouth that I am born again!!!
