In the New Testament circumcision is regarded as spiritual and inward. Paul said it quite emphatically, “Neither is that circumcision which is outward in the flesh... circumcision is that of the heart” (Rom. 2:28-29). “We are the circumcision, who worship by the Spirit of God” (Phil. 3:3). It is a spiritual thing, an inward thing; it is of the heart. And it simply means that in the Cross of the Lord Jesus, the natural life and the reasoning of the natural life, or the self-life – the willing of the self-life, the desiring of the self-life – has been cut off by the Cross. Every expression and aspect of the self-life has been cut through by the Cross and is put in the place where the door is shut. There is no open door to any expression of the natural life. The Cross says, "The door is closed; death rests upon that." That is spiritual circumcision.
Stephen, in that matchless discourse of his which resulted in his murder, cried at one point to those who were persecuting and about to stone him, “Ye stiffnecked and uncircumcised in heart” (Acts 7:51). What did he mean by “uncircumcised in heart and ears”? He just meant this, that they were only willing and minded to have what they wanted and nothing more. Prejudice is a certain mark of an uncircumcised heart. Bigotry is the same, and anything that you can find that made up the situation which brought Stephen to his death is a mark of an uncircumcised heart. That is the thought. Still there is the reasoning and the arguing of the Self, of the natural life. There is still the desiring and the feeling of the Self obtruding itself. The Cross, spiritual circumcision, says "No!" to it all.
