As we continue our study of how Christ was administered to the Saints in the Old Testament, we move now to the Law of God.  We have so far discussed the Seed, the Land, Circumcision, and the Sacrificial System, all of which were shown to be “for that time, sufficient and efficacious, through the operation of the Spirit, to instruct and build up the elect in faith in the promised Messiah, by whom they had full remission of sins, and eternal salvation” (The Westminster Confession of Faith, Ch. 7.5). Of course, each of these are included in God’s Law as broadly defined, so we have done much of our work already.
