And the Lord thy God will circumcise thine heart, and the heart of thy seed, to the Lord thy God with all thine heart, and with all thy soul that thou mayest live. (Deuteronomy 30:6)
Here we read of the true circumcision. Note the author of it: “The Lord thy God.” He alone can deal effectually with our heart and take away its carnality and pollution. To make us love God with all our heart and soul is a miracle of grace which only the Holy Ghost can work. We must look to the Lord alone for this and never be satisfied with anything short of it.
Note where this circumcision is wrought. It is not of the flesh but of the Spirit. It is the essential mark of the covenant of grace. Love to God is the indelible token of the chosen seed; by this secret seal the election of grace is certified to the believer. We must see to it that we trust in no outward ritual but are sealed in heart by the operation of the Holy Ghost.
Note what the result is – “that thou mayest live.” To be carnally minded is death. In the overcoming of the flesh, we find life and peace. If we mind the things of the Spirit, we shall live. Oh, that Jehovah, our God, may complete His gracious work upon our inner natures, that in the fullest and highest sense we may live unto the Lord.
