Galatians 5:2-6

Notice, it is I, Paul, who tells you that if you receive circumcision [as a supposed requirement of salvation], Christ will be of no benefit to you [for you will lack the faith in Christ that is necessary for salvation]. Once more I solemnly affirm to every man who receives circumcision [as a supposed requirement of salvation], that he is under obligation and required to keep the whole Law. You have been severed from Christ, if you seek to be justified [that is, declared free of the guilt of sin and its penalty, and placed in right standing with God] through the Law; you have fallen from grace [for you have lost your grasp on God’s unmerited favor and blessing]. For we [not relying on the Law but] through the [strength and power of the Holy] Spirit, by faith, are waiting [confidently] for the hope of righteousness [the completion of our salvation]. For [if we are] in Christ Jesus neither circumcision nor uncircumcision means anything, but only faith activated and expressed and working through love.
