Yes, I am 100% sure that I will go to heaven.
1. I belong to a good church and go regularly.
What then must I do?
Well, here's what the Bible says: 'Whosoever shall call upon the name of the Lord shall be saved,’ and ‘as many as received Him [Jesus], to them He gave power to become the sons of God’” (Romans 10:13; John 1:12).
“But will Jesus receive me? I done some rather obvious sinful things in my past.”
Jesus said, ‘He that comes to me I will in no way refuse’ (John 6:37). He loves you. Yes, He died for you. He took the punishment for your sins on the Cross of Calvary. Trust not in your own ways, but completely in His work to wash your sins clean. As scripture says, He is the only way to reconcile your wrongs with God. Because He died for your wrongdoing, you may go free instead of facing judgment. He also commands your repentance: that is, that you turn from running your own life and follow Him with all your heart.
