1 Peter 2:24 "Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness by whose stripes ye were healed"
The Bible tells us that carried our sins away and His death made us dead to sins and by His stripes, we are made whole. In the Bible, when the word "wholeness" is mentioned, it means "Healing". One of the purpose of the Life of Jesus on earth, was to give us wholeness- healing of our body, soul and spirit bringing restoration to our fellowship with the Father. Also, He came to redeem all that was lost in the beginning after the first sin of man and reconcile us back to God.
Colossians 2:10
"and in him you are made full, who is the head of all principality and power."
We see that we are complete in Christ Jesus, who is the head over all principality and power and we don‘t have to wonder why Jesus decided to save us because He came to give us wholeness.
As Christians, we are meant to be whole and free from sickness. We should not allow the devil steal from us because Jesus has given us authority over the devil.
All things are ready for the taking and for the receiving. We are blessed with all spiritual blessings in heavenly places before we were born and we must not give in what people may say about us here on earth but set our eyes on heaven.
