Romans 10:9 says, “if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.”
Confess and believe. That’s all it takes to be saved. You can confess to Jesus in your own words, or pray the following:
"Dear Lord Jesus, I admit that I’ve fallen short. I’ve sinned and need your forgiveness. I believe that You lived, died, and rose again so that I could be connected to God. I confess you as my Lord and commit my life to You. I give you my past, present, and future. Take my life and use it. I give it to You. Amen."
