Gal 3:8 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.
Gal 3:16 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. Jhn 3:6 That which is born of the flesh is flesh; (first part) Hbr 5:7 Who in the days of his flesh, when he had offered up prayers and supplications with strong crying and tears unto him that was able to save him from death, and was heard in that he feared; Hbr 5:8 Though he were a Son, yet learned he obedience by the things which he suffered; Hbr 5:9 And being made perfect, he became the author of eternal salvation unto all them that obey him; Act 2:32 This Jesus hath God raised up, whereof we all are witnesses. Act 2:33 Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear Gal 3:14 That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith.
I think I said in a previous post that the definite article the is before the word faith in the greek of Gal 3:14 which I think would be understood as the faith of Christ. When you think about it the only being that would ever need faith would be lets say that had been immortal but gave that up and became something lower that could die. Man was made mortal. I don't care how many parts you want to give him body, soul and spirit they were all mortal subject to corruption. I am not going to post all of it but read 1 Cor 15:44-50 Man was made mortal, earthy, natural, flesh and blood and so was the Word who became flesh. I asked before why the Christ would need the sure mercies of David?Act 13:34 And as concerning that he raised him up from the dead, [now] no more to return to corruption, he said on this wise, I will give you the sure mercies of David.
Because the Word became flesh.
