Deuteronomy 26:18

Hath owned thee for such before all the world by eminent and glorious communications and manifestations of his power and grace and favour in time and for thee, by a solemn entering into covenant with thee, and giving peculiar laws, promises, and privileges to thee above all mankind. That thou shouldest keep all his commandments; which is here mentioned as an act of God s, because though this be man's duty, yet it is the work of God's grace, that he will vouchsafe to give us such commands, that he doth require and will accept of our obedience to them, and that we have any power or will to obey them, Ezekiel 36:26,27.
