The Lord thy God will circumcise thine heart, to love the Lord thy God - Deuteronomy 30:6

Circumcision is the sign of separation. It was enjoined on Abraham and his children that they might be God's peculiar people, chosen from all the nations of the earth. Similarly, the circumcision of Christ, which is made without hands, of which the Apostle speaks, is a putting off, a separation from the sins of the flesh, a participation in the grave and burial of Christ (Col 2:12).
 
We must be separated from the spirit and temper of the world. Between us and its sins, ambitions, methods, there must be not only an outward, but a heart severance. We were separated in the purpose of God when Jesus was cast without the camp to die. But we must be separate in our personal behavior. Wouldst thou have this? Then claim that this promise should be fulfilled, and ask that God would circumcise thine heart - the seat of thine affections, the hearth of thy soul-life.
 
Then thou wilt love the Lord with all thine, heart. This is why we love God so little. The force of our love is spread over too wide a sur-face-it is like the river Orinoco, which is lost in swamps as it approaches the sea. If only we were really separated from all that is alien to God, and. given up to Him wholly, we should find all the capacity of our hearts becoming filled with His love. We should love all things and people with a tenderness and glow which were steeped in colors obtained from His.
 
You will never succeed in overthrowing the strongholds of Satan, Christian worker, till God has taken away your self-reliance, and has brought you down into the dust of death: then, when the sentence of death is in yourself you will begin to experience the energy of the Divine life, the glory of the Divine victory.
