 Put your faith in him that he did it for you. He will give you everlasting life. The moment you believe that payment he made is good on your account and all of your sin is removed, you are righteous in the eyes of God. You are declared righteous. You have everlasting life. You'll never come into condemnation. You've passed from death unto life. You become a child of God. That moment, reservations are written for you in heaven.
