11 In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ:
English Standard Version
11 In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ,
11 Entering into this fullness is not something you figure out or achieve. It's not a matter of being circumcised or keeping a long list of laws. No, you're already in - insiders - not through some secretive initiation rite but rather through what Christ has already gone through for you, destroying the power of sin.
New King James Version
11 In Him you were also circumcised with the circumcision made without hands, by putting off the body of the sins of the flesh, by the circumcision of Christ,
New Living Translation
11 When you came to Christ, you were "circumcised," but not by a physical procedure. Christ performed a spiritual circumcision-the cutting away of your sinful nature.
There is a philosophy which rightly exercises our reasonable faculties; a study of the works of God, which leads us to the knowledge of God, and confirms our faith in him. But there is a philosophy which is vain and deceitful; and while it pleases men's fancies, hinders their faith: such are curious speculations about things above us, or no concern to us. Those who walk in the way of the world, are turned from following Christ. We have in Him the substance of all the shadows of the ceremonial law. All the defects of it are made up in the gospel of Christ, by his complete sacrifice for sin, and by the revelation of the will of God. To be complete, is to be furnished with all things necessary for salvation. By this one word "complete," is shown that we have in Christ whatever is required. "In him," not when we look to Christ, as though he were distant from us, but we are in him, when, by the power of the Spirit, we have faith wrought in our hearts by the Spirit, and we are united to our Head. The circumcision of the heart, the crucifixion of the flesh, the death and burial to sin and to the world, and the resurrection to newness of life, set forth in baptism, and by faith wrought in our hearts, prove that our sins are forgiven, and that we are fully delivered from the curse of the law. Through Christ, we, who were dead in sins, are quickened. Christ's death was the death of our sins; Christ's resurrection is the quickening of our souls. The law of ordinances, which was a yoke to the Jews, and a partition-wall to the Gentiles, the Lord Jesus took out of the way. When the substance was come, the shadows fled. Since every mortal man is, through the hand-writing of the law, guilty of death, how very dreadful is the condition of the ungodly and unholy, who trample under foot that blood of the Son of God, whereby alone this deadly hand-writing can be blotted out! Let not any be troubled about bigoted judgments which related to meats, or the Jewish solemnities. The setting apart a portion of our time for the worship and service of God, is a moral and unchangeable duty, but had no necessary dependence upon the seventh day of the week, the sabbath of the Jews. The first day of the week, or the Lord's day, is the time kept holy by Christians, in remembrance of Christ's resurrection. All the Jewish rites were shadows of gospel blessings.
