Deuteronomy 30:15-19

Reader! while you and I attend to the close of Moses' Sermon, and hear the solemn appeal which the animated preacher makes to heaven, that he had executed his commission, and fully discharged his duty in referring the people to their choice: let us learn to bless GOD, that we are not only taught these things, but that we have the promise of grace, to enable us to perform them. Blessed be GOD! JESUS is the mediator of a better covenant, established upon better promises. The law made no provision for defect or inability. The law made nothing perfect. But the bringing in this better hope, hath done it in JESUS, by the which we draw nigh unto GOD. Hebrews 7:19.
