Its time to get right with Jesus. nobody is automatically gonna go to heaven at the end of it, we all have lied or stolen or had sex before marriage and the punishment is hell. Jesus died so you can get a clean slate and forgiveness of future sins if you repent of them if you commit them, so you receive the gift of forgiveness by following him. When you start you have to stop sinning willfully, and follow his word and obey it, strive to do those things. That’s following the Lord Jesus. Read the Bible and find wisdom
