Gal.3.19

Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator.

Gal.3.19

The purpose of the law was to keep a sinful people in the way of salvation until Christ (the descendant) came, inheriting the promises and distributing them to us. Obviously this law was not a firsthand encounter with God. It was arranged by angelic messengers through a middleman, Moses.

Gal.3.19

What, then, was the purpose of the law? It was added because of transgressions until the Seed to whom the promise referred had come. The law was put into effect through angels by a mediator.

Gal.3.19

Well then, why was the law given? It was given to show people how guilty they are. But this system of law was to last only until the coming of the child to whom God's promise was made. And there is this further difference. God gave his laws to angels to give to Moses, who was the mediator between God and the people.
