 You're going to heaven. You're locked in. You're sealed by the Holy Spirit until the day of redemption, the Bible says. But when you sin, as Paul said, don't grieve the Holy Spirit of God. Don't quench the Holy Spirit of God. When you allow your personal faults to surface and you sin, you break fellowship with God and you are no longer filled with the Holy Spirit. Paul gave some insight into this personal conflict in his letter to the Galatians.
