Because you are in Christ, you already have something called "the blessing of Abraham." You do not need to get it. You already have it now. You don't receive it by your works. You received it when you were saved. Whether you ever walk in the light of it or not, Abraham's blessing is yours already!
Let's prove this in Galatians 3:
"Know ye therefore that they which are of faith, the same are the children of Abraham. And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed. So then they which be of faith are blessed with faithful Abraham." -- Gal 3:-7-9.
"Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree: that the blessing of Abraham might come on the Gentiles, through Jesus Christ; that we might receive the promise of the Spirit through faith." -- Gal 3:13-14.
"Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ." -- Gal 3:16.
"And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise." -- Gal 3:29.
You are a partaker of the blessing of Abraham because you are in Christ. It has nothing to do with your works.
One of the conspicuous blessings Abraham had was great wealth. This is why you should not run around acting and talking like the devil is keeping money away from you. If you say that, he'll be happy to mess with your money, but the truth is, he can't keep it from you because you already have the blessing of Abraham. You're not trying to get it. You have it now. You just need to act and talk in agreement with that.
What does this have to do with healing, and why is this included in a discussion of healing? Abraham enjoyed good health. Isaac was born to him when he was a hundred years old. Years later he was able to climb a mountain to offer Isaac as a sacrifice. This guy was definitely in good shape for that age. And that's not all! When Sarah died, Abraham remarried -- and had six more kids by his second wife (Gen 25:1-3)! In all, Abraham lived 165 years (Gen 25:8). Long life was one way that God blessed him.
Yeah, but can we really think that health is part of the blessing of Abraham? You can think what you want, but what Jesus thought is in Luke 13:11-16. Jesus said that the woman ought to be healed because she was a daughter of Abraham. It appears that Jesus considered good health to be part of the blessing of Abraham, which you now have. Therefore, you should enjoy this part of the blessing. Remember, this blessing is already yours. You're not trying to get it -- you already have it! Act and talk in a way that reflects that fact.
Healing and prosperity
