Jesus the Redeemer

"Christ has redeemed us from the curse of the law, having become a curse for us (for it is written, 'Cursed is everyone who hangs on a tree')."
-Galatians 3:13 

You can go back to Deuteronomy ch. 28 and see what the curse of the law is; it is sickness and disease, scabs, cancers, sores, poverty, desolation, etc. Jesus redeemed us from the Curse of the Law, by becoming a curse for us. Jesus, being God, took the punishment we deserved and made it so that now we as Christians will never be punished.

"...By Whose stripes you were healed."
-1 Peter 2:24

Because of what Jesus did on the Cross, we have already been healed of all sickness physical, emotional and spiritual! We are, right this moment, healthy as can be in our born-again spirit. Jesus accomplished everything on the Cross at Calvary, and now we just have to reach out by faith into our spirit and receive what he has given us.

"By faith we understand that the world were framed by the word of God, so that the things which are seen were not made of things that are visible."
-Hebrews 11:3

The parent force is greater than the child force; in the dawn of time, God created the heavens and the earth... the spirit force, created the physical world around us. What you see in the physical was made by the parental spiritual world. What goes on the spirit is the ultimate reality, while everything in the carnal realm must follow what happens in the spiritual realm. If you are healed and prospered in the Spirit, then if you take God's Word concerning that by absolute trust and faith it will have to come to pass in the visible realm.
