Here’s a simple prayer you can pray, or use your own words to express to God your desire:
God, please forgive me for all my sins: for trying to be my own savior, and for my pride and self-focus. I believe Jesus died on the cross for me and rose again. Thank you for sending your Son to be my Lord and Savior. Jesus, I thank you for loving me, coming into this world for me and showing me the way to live in you now and forever. I commit my life to you. Help and lead me. Amen.
