If you want to repent and turn to God, you can pray this simple prayer. What matters is the attitude of your heart rather than the words themselves.
If you are truly sorry and want to turn from your sins, God will forgive you, and you will experience his peace and joy.
You can pray like this:
Heavenly Father, I admit I’ve sinned many times against you and against other people. I admit I’ve ignored you and lived for myself, as if you didn’t exist. But today I repent and turn from my sins and my selfish ways to serve you. I come to you as I am and surrender my life to you. Please forgive me and wash me clean. I put my trust in the sacrifice of your son Jesus on the cross. Please lead me and guide me through your Holy Spirit so I can live a life pleasing to you. I pray in the name of Jesus.
If you prayed this prayer and meant it, welcome to the worldwide family of God!
Keep praying and seeking God. Read the Bible and do what it says. Get together with like-minded believers. Sanctify your life.
Get closer to God, and he will get closer to you.
