Romans 10:9-10 "That if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved."
Basically just Believe in the Lord and just because you get saved doesn't mean you can go around and do all this bad stuff again, you also have to try not to sin and have a relationship with God and get to know him more!
A way to get a relationship with God is reading your bible, telling God how you feel by praying because if you have anything you want to say to God like questions, or things about your family, or trauma happening in your life you can go to God and he'll do what he do.
Amen!
