If you believe that the Bible offers truth about the way to savation, but you have not made the decision yet to become a Christian, it's as simple as praying this prayer. You can pray by yourself, using your own words. There is no special formula. Just pray from your heart to God, and He will save you. If you feel lost and just don’t know what to pray, here’s a prayer of salvation that you can pray:
Dear Lord, I admit that I am a sinner. I have done many things that don’t please you. I have lived my life for myself. I am sorry and I repent. I ask you to forgive me. I believe that you died on the cross for me, to save me. You did what I could not do for myself. I come to you now and ask you to take control of my life, I give it to you. Help me to live every day in a way that pleases you. I love you, Lord, and I thank you that I will spend all eternity with you.
