Romans Chapter 2

Romans 2:17-24 ~ The Position and Pride of the Jews in the Law

All of this, While having a form of the knowledge and of the truth and the law. A form. The Greek word means an outline. A shape but no substance. So you have it down in form but there is no substance because Jesus Christ is the substance of all that the Old Testament was talking about. All of the feasts, all of the sacrifices, even the items in the Tabernacle all pointed to Jesus Christ. So they had this outward expression, but inwardly they are like dead men's bones.

Romans 2:25-29 ~ Spiritual Circumcision

Jesus brought this out when He says, "The one who knows the most is the most responsible." And the Hebrew person does not know that the more they study the Law, and the more they become experts in knowing the Law, that makes them more responsible than anybody. The same with the believer in studying God's word. Most of it is head knowledge for us. But God holds us responsible not only to preach it, but to do it.
