Did God give the law to Moses on stone tablets or on lambskin?
God gave the Law to Moses on stone, not on lambskin. The transcript contrasts the two, asking whether it was given on a beautiful piece of lambskin and answering no; it was given on cold stone. This reflects the Law’s unyielding, non-cuddly character.
Les explains that, way back in Exodus, God did not give the Law to Moses on a beautiful piece of lambskin; He gave it on cold stone. Stone is not cuddly, not warm, and not something you can bring to yourself—that picture fits the Law. The Law was perfect from God’s point of view, the very mind of God, but from man’s point of view it was weak and beggarly because man could not keep it; there was no power in the Law to help him keep it. Paul therefore says, 'For I through the law am dead to the law, that I may live unto God,' which is Romans 7 all over again.
For I through the law am dead to the law, that I might live unto God.
