In July 1792, James Hoban was named winner of the design competition for the White House. The structure was later fleshed out according to Hoban's architectural blueprint. The actual White House which we see at 1600 Pennsylvania Avenue, is the fulfillment of Hoban's plan. The actual White House and Hoban's plan are separate and distinct, even so there's consistency between the two.
We can learn much from the relationship between Hoban's blueprint and the actual White House, and we can apply this analogy to the relationship between Christ and His Law, since Christ is the fulfillment of the Law.
Using Hoban's plan, it's possible to determine much about the actual structure of the White House, specifically dimensions and things hidden beneath the paint. The structure will not conflict with the design, there will be consistency between the two. Likewise we can determine much specifically about Christ by studying His Law. There is no conflict between Christ and His Law, there is only consistency. The ever-consistent moral character of God is exhibited consistently throughout both.
Inscribed in the written Law of God we find the true character of God spec'd out. Christ said about the Law:
"You shall love the Lord your God with all your heart, and with all your soul, and with all your mind. This is the great and foremost commandment. The second is like it, You shall love your neighbor as yourself. On these two commandments depend the whole Law and the Prophets." - Matthew 22:37-40 (NASB).
In the Law of God we see spec'd out what love to God and love to our neighbor really looks like. For example, in Leviticus we find:
"Also you shall not approach a woman to uncover her nakedness during her menstrual impurity. You shall not have intercourse with your neighbors wife, to be defiled with her. You shall not give any of your offspring to offer them to Molech, nor shall you profane the name of your God; I am the Lord. You shall not lie with a male as one lies with a female; it is an abomination. Also you shall not have intercourse with any animal to be defiled with it, nor shall any woman stand before an animal to mate with it; it is a perversion." - Leviticus 18:19-23 (NASB)
We can look at these commandments and see real love spelled out, not the counterfeit love that many often fabricate apart from God's Law. Anybody can say their house is the White House; Hoban's blueprint will discover your lie. Anybody can say they love God and their neighbor; God's Law will put you to the test. Those who envision an inconsistency between Christ and His Law will be found to be envisioning a counterfeit God.
