The Old Testament is talking about physical circumcision as a sign or seal the agreement, between God and Abraham and his descendants, upon granting the truth of God, where God chooses and marks his own people.
“And God said unto Abraham, Thou shalt keep my covenant therefore, thou, and thy seed after thee in their generations. This is my covenant, which ye shall keep, between Me and you and thy seed after thee; Every man child among you shall be circumcised. And ye shall circumcise the flesh of your foreskin; and it shall be a token of the covenant between Me and you. “(Genesis 17 :9-11)
“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: 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.” (Romans 4:11-12).
In addition each member is required to express it outwardly agreement with obeying the law of God, with the firm are also required to Abraham: “I am the Almighty God; walk before me, and be thou perfect.”(Genesis 17:1).
Circumcision is outwardly manifest, implement the promise and called on people to live in obedience based on the agreements that have made expensive demands of God, which is demanding the reality of its application according to the sign of circumcision, the Word of God says … .. I will punish the people who have been circumcised foreskin … .. because all nations are not circumcised and all the people of Israel uncircumcised heart (Jeremiah 9:25-26).
Can we on the demands it?
Therefore the Lord Jesus came to fulfill the law, “Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill.” (Matthew 5:17).
The New Testament clearly and definitely say that without obedience, physical circumcision is futile. In Romans 2:23-29 says: “You boast in the law, do you dishonor God by breaking the law? As it is written: “because of you the name of God is blasphemed among the Gentiles.”
Circumcision is of no use, if you obey the law, but if you break the law, your circumcision you no longer use. So if the uncircumcised attention to the demands of the law, would not he be considered the same as people who have been circumcised? If so, then the person who is not circumcised, but that the law, will judge you who have written law and circumcision, but who violate the law.
Because the so-called Jews are not the ones who outwardly Jewish, and the so-called circumcision, circumcision is not the place it outwardly. But the true Jew is he who does not look Jewish and circumcision is circumcision of the heart, spiritually, not literally. And the praise is not from men but from God. “
Circumcision is of no use, if you obey the law, but if you break the law, then your circumcision is no longer any good. Outward sign of fade without meaning when compared to obey God’s commandments. “If a state is called in uncircumcision, he must not try to negate the sign of circumcision. And if a call in a state not circumcised, he must not want to be circumcised. For neither circumcision nor uncircumcision important. The important thing is to obey the laws of God. “(1 Corinthians 7:18-19).
Long before the New Testament, the Word of God had said in Deuteronomy 10:16, “Therefore circumcision is your heart and do not you rigid neck again.”
So the heart circumcision is not a new command in the New Testament but already since the time of the Old Testament when Moses received the command of God to the Israelites.
Therefore we need a “Circumcision of Christ” or the circumcision of the calendar will be the body’s heart is sinful that is a spiritual act that was not done by human hands but a relationship with Christ in His death and resurrection.
The Word of God in Colossians 2:13 says: “You too, although you were dead by the offense and therefore is not circumcised outwardly, has turned God along with Him, after He forgave all our sins, by eliminating debt, which by legal provisions to charge and threaten us. And that eliminated him by nailing on the cross. “
All were sealed by the regulatory acceptance of new agreements, “In Him you were circumcised, not with a circumcision done by humans, but with the circumcision of Christ, which consists of the calendar will be the body of sin, (Colossians 2:11-12).
So a Christian is one who circumcised himself, “It is we the people circumcised hearts, who worship by the Spirit of God and glory in Christ Jesus and put no confidence to the flesh. “Therefore circumcision is your heart and you do not anymore rigid neck” (Deuteronomy 10:16).
