I said that Abraham was never under the law and you ask, "Are you kidding?"
Are you not aware that he was never under the law, including the things of the law in regard to ceremonial cleansing? Here is what you said earlier:
Let us look at this passage again:
"What shall we say then that Abraham our father, as pertaining to the flesh, hath found? For if Abraham were justified by works, he hath whereof to glory; but not before God. For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness. Now to him that worketh is the reward not reckoned of grace, but of debt. But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness" (Ro.4:1-5).
The words here which are in "bold" are quoted from Genesis 15:6. That event happened before Abraham was circumcised (Gen.17) so what Paul wrote at Romans 4:1-5 has nothing at all to do with circumcision. Paul says that if a person's justification before God is based on "works" then that justification cannot be described as being of "grace."
Those two things are mutually exclusive!
Your ideas about grace prove that you do not even understand the "gospel of grace" because you say that we cannot be justified or saved by grace unless we do the work of obeying the Lord Jesus. And since you do not understand that gospel you surely cannot believe it.
It is only those who "believe God" who are justified in the eyes of the Lord:
"For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness" (Ro.4:3).
You are deluding yourself if you actually think you are believing what the Lord says about being justified in His sight by "grace." It is only those who actually believe that gospel who are saved:
"For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth" (Ro.1:16).
Repent and believe the "gospel of grace." Cease from your ugly business of trying to convince others that no one can be saved apart from works.
