And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ. 1 Thessalonians 5:23
Some people get confused about when salvation happens. Let me see if I can shed some light on this. Salvation can be explained if you think of it this way—your past, your present, and your future.
The moment you repented and believed on Jesus Christ as your Lord and Savior, a chain reaction started in your life.
When you ask Jesus to forgive and save you, immediately you are justified in your spirit. You are sanctified progressively in your soul. And you will be ultimately glorified in your body. You are saved from sin’s penalty, its power and one day even its presence.
I have good news: The preservation of your salvation is God’s job—not yours. Praise Him for that as you stop working so hard, and trust in Him instead.
