Talk to a priest

Romans 10:9-10 says 9 "That if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. 10 For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation." this is what the Bible says to do for salvation. Jesus died for all of your sins and he rose from the dead so that you can be forgiven of all of your sins and so that you can have eternal life If you repent of your sins and admit that you were wrong and that you can’t do it on your own and that you need Jesus, and if you give your life to him you will be saved. So please get a relationship with Jesus and follow and do what he says and of course that will not go prefectly we will all still make mistakes, but just know that Jesus died for all those mistakes and trust them
