Faith's Checkbook (By: C.H. Spurgeon)

                                                                    Mark of Covenant Grace

The Lord your God will circumcise your heart and the heart of your descendants, to love the Lord your God with all your heart and with all your soul, that you may live.
                                                                                ~ Deuteronomy 30:6

  "Note the words, "The Lord your God." He alone can deal effectually with our hearts and take away their carnality. To make us love God with all our hearts and souls is a miracle of grace that only He 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. 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 you may live." To be carnally minded is death. In the overcoming of the flesh we find life and peace. Oh, that God may complete His gracious work upon us, that we may live unto Him." (By: Charles H. Spurgeon ~ One Minute Devotions)
