The Mosaic covenant, while being an administration of the covenant of grace, was a “legal administration.”
This means that it came along with a rigorous reapplication of the law of God broken in Eden, and many
statutes and commandments intending to teach the people of God “under age” as minors, so to speak, not to look for salvation in their
own works, as if the commandment had never been broken in Eden, but to look to Him who was to come. The
Judaizers in Paul’s day were misusing the Mosaic law by trying to make it a way of salvation, which it
was never intended to be, since Israel at Sinai had already broken God’s law in Adam, and in many other sins.
Now the Church has reached a mature stage compared with the Church at Sinai. We do not need all the “picture books”
and ceremonies. But looking back, we nonetheless see that the Mosaic covenant was one and the same with the New
John 1:16 nkj And of His fullness we have all received, and grace for grace. 17 For the law was given through Moses, but grace and truth came through Jesus Christ.
These verses do not describe a difference in kind between the covenants of Moses and Christ, but an increase in degree of the same kind of thing. “grace for grace”
