Colossians 2:10. "And ye are complete in him, which is the head of all principality and power:"
NO ADDITIONS NEEDED. Salvation is a finished work, it would be wrong to say, "Jesus and..." To pay the price of redemption by any works is beyond the ability of man. God is supreme in every way, not just in creatorial power; Every government and every force, is in relation to God's, very much lower.
Yet He who is so preeminent that He is the head of all things, Has made anything we could do, unnecessary for we are complete in Him. We need no "out-of-the-body" experiences; we need no angels or men; To make us more fit to be in the presence of God - we are complete in Him.
Any additional work we would try; any sacrifices we would bring, Would only bring the value of what Christ has done down, we are complete in Him. The suffering of pain; the money we earn - even the hymns we sing, Would only add sin polluted stains to His work, for we are complete in Him.
When people make comments like, "I go to church regularly and I pray." As a reply to them, from scriptures of truth in the Bible I say, "Listen to what the Word of God says, lest you make a mistake and are lost." "For by grace are ye saved through faith… not of yourselves...lest any man should boast."
Our completeness makes us fit for the presence of God, of His fullness have we received. He gives His grace freely for the grace we need, and that is based on Him who we believed. His work is complete and we are complete in Him, with that God is satisfied. His righteousness imputed to me is what is acceptable, it was for me Jesus suffered and died.
To add anything to such a complete work would be insulting to say the least. To imply that anything I add to Christ's work, would bring to the both of us grief. All of the glories of man put together, fade into insignificance in the light of God's grace. The awareness of being complete in Him, is one of the strongest motivations to live by faith.
"Father, I thank Thee for this sense of completeness that gives rest to my soul and mind. I am not struggling to be made right with Thee. Bit I am certainly motivated to serve Thee. Help me to be effective today. In the name of the Lord Jesus Christ, Amen."
