RIGHT! The law could NOT produce the righteousness needed for Salvation. The law, in and of itself, could not reproduce love! Christ, with the law inside Him, could. Therefore He was perfect!
Why do you think that Gentiles are called unnatural branches??? Why are the Jews considered natural??? Whats the difference? Do we have different organs? Is it the color of skin?
NO! Its the background of that which is true, pure, holy, just, and good. They have, by nature, this natural ability to pass on the fruit that the root/vine sends out. The only difference in Gentiles and Jews is the LAW! They are "tame", we are "wild". We are grafted into the "tame" vine, they are NOT grafted into the "wild" vine.
That is very good observation. Let's look at what Paul says about it:
Romans 3:1 "What advantage then hath the Jew? or what profit is there of circumcision?
2 Much every way: chiefly, because that unto them were committed the oracles of God.
3 For what if some did not believe? shall their unbelief
make the faith of God without effect?"
Now, do we see how Paul boils down what he said to what I emboldened and underlined there?
That is important so that we do not mistakenly think he is saying that of all Israelites just because they are Israelites as to the flesh.
Paul is showing that it was in that fleshly nation that God first chose men of faith to rule with Christ from among the fleshly Israel and these men of faith were the real Israel of God. It was only the men of faith in that nation that were able to benefit as Nathan has described. And therefore only those Israelites who had faith are those natural branches. They are a remnant ('remaining ones' or 'the only ones to remain') as compared to the total fleshly Israel.
Thus we understand better what Paul said here:
Romans 9:3 "For I could wish that myself were accursed from Christ for my brethren, my kinsmen according to the flesh:
4 Who are Israelites; to whom pertaineth the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises;
5 Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen.
6 ¶Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel:
7 Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called.
8 That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.
Now these words of Paul are amplified:
Galatians 3:24 "Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
25 But after that faith is come, we are no longer under a schoolmaster.
26 For ye are all the children of God by faith in Christ Jesus.
27 For as many of you as have been baptized into Christ have put on Christ.
28 There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
29 And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise."
This is why I so often have emphasized Paul's words, (Galatians 3:22) "But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe."
When God pronounced the death sentence on Adam is when all were confined under sin. No flesh could be born to God from Adam or born with the ability to themselves bear children to God. The Law written against sin was added to prove that of the flesh while at the same time God's grace in Christ reached back making its selection based on faith as it did from Abel to Abraham and continued to do right on through fleshly Israel for the purpose of leading us to Christ.
Is there anyone who is having difficulty grasping that?
