Isai 33:22 For the LORD [is] our judge, the LORD [is] our lawgiver, the LORD [is] our king; he will save us. {lawgiver: Heb. statutemaker}
Truly, the Lord is "Our Lawgiver" for He is the Author of all Law. He made the first Law: "In the day that thou eatest thereof thou shalt surely die," --- a simple, definite Law. When Adam and Eve violated that Law, they suffered the penalty, "dying, they began to die." God never changed that "Law of sin and death," but He made a new Law, "the Law of the Spirit of Life in Christ Jesus" (Ro 8:2) which makes us "free from the Law of sin and death," so that we who were born sinners --- hopeless, helpless --- receiving Christ as Saviour are, through that new Law, freed from sin and death and made eternal children of God.
Thou blessed "Lawgiver" we thank Thee for that wonderful new Law, and for our Salvation through obedience to it. Amen.
