Your spiritual salvation is complete. Nothing can be added to it. In your spirit, you are right now as you will be throughout all eternity.
The Christian life is not like an insurance policy that only pays off when we die and go to heaven. Every believer has now received the grace of God and the fullness of God. We are now complete in Him (Colossians 2:9-10).
When we receive Jesus as our Lord, we are instantly changed in our spirits (2 Corinthians 5:17). Many Christians aren't aware of the change that takes place in their spirit. They continue to live within their physical and emotional realms and are oblivious to the new, born-again part of them that has received the fullness of God.
You can't see or feel your spirit. You just have to believe what the Word of God tells you because God's Word is spirit and life (John 6:63). Your spiritual salvation is complete. Nothing can be added to it. In your spirit, you are right now as you will be throughout all eternity (1 John 4:17). PRAISE THE LORD!
To the degree that we will renew our minds to these truths and believe them, we will experience this fullness in this life, for as a man "thinketh in his heart, so [is] he" (Proverbs 23:7).
Pray the prayer of Ephesians 1:15-23 and let the Holy Spirit reveal "Christ in you, the hope of glory" (Colossians 1:27).
