How about READING your bible, ALL of it, and then lets talk about salvation.
Is circumcision of the penis or of the heart?
Inward or outward JEWS of Israel?
(Joh 7:22) Moses therefore gave unto you circumcision; (not because it is of Moses, but of the fathers;) and ye on the sabbath day circumcise a man.
(Act 10:45) And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost.
(Act 11:1) And the apostles and brethren that were in Judea heard that the Gentiles had also received the word of God.
(Act 11:2) And when Peter was come up to Jerusalem, they that were of the circumcision contended with him,
(Act 11:3) Saying, Thou wentest in to men uncircumcised, and didst eat with them.
(Rom 2:25) For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
(Rom 2:27) And shall not uncircumcision which is by nature, if it fulfill the law, judge thee, who by the letter and circumcision dost transgress the law?
(Rom 2:28) For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:
(Rom 2:29) But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
(Rom 3:1) What advantage then hath the Jew? or what profit is there of circumcision?
(Rom 3:2) Much every way: chiefly, because that unto them were committed the oracles of God.
(Rom 3:3) For what if some did not believe? shall their unbelief make the faith of God without effect?
(Rom 3:4) God forbid: yea, let God be true, but every man a liar; as it is written, That thou mightest be justified in thy sayings, and mightest overcome when thou art judged.
(Rom 3:30) Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.
(Rom 3:31) Do we then make void the law through faith? God forbid: yea, we establish the law.
I'll end this post with this. Obviously, there as much more then the house of Israel. What made you part of the house of Israel?
(Rom 4:10) How was it then reckoned? when he was in circumcision, or in uncircumcision? Not in circumcision, but in uncircumcision.
(Rom 4:11) And he received the sign of circumcision, a seal of the righteousness of the faith which he had yet being uncircumcised: that he might be the father of all them that believe, though they be not circumcised; that righteousness might be imputed unto them also:
(Rom 4:12) And the father of circumcision to them who are not of the circumcision only, but who also walk in the steps of that faith of our father Abraham, which he had being yet uncircumcised.
(Rom 4:13) For the promise, that he should be the heir of the world, was not to Abraham, or to his seed, through the law, but through the righteousness of faith.
(Rom 4:14) For if they which are of the law be heirs, faith is made void, and the promise made of none effect:
(Rom 4:15) Because the law worketh wrath: for where no law is, there is no transgression.
(Rom 4:16) Therefore it is of faith, that it might be by grace; to the end the promise might be sure to all the seed; not to that only which is of the law, but to that also which is of the faith of Abraham; who is the father of us all,
