It appears that you completely misunderstand the Sacrifice on the Cross as well as the Gospel of the Grace of God...
Jesus died on the Cross because there is nothing we could do to provide the sacrifice necessary for Salvation...He paid our price; all of it...Jesus became sin, for us...Jesus gave us His righteousness, because we couldn't produce or provide any ourselves...We are incapable...
Jesus gave this free gift to the Gentiles, the pagans to make His people Israel jealous...
Amen
Jesus gave this free gift to the Gentiles, the pagans to make His people Israel jealous
Agree completely. Our works, and our suffering contribute to our salvation because of the redemptive work of Jesus on the Cross, and never under our own power.
