*sigh. Your childishness and arrogance are as taxing as my 6 year old. Forgive my comment but to me, you are.
Does not Leviticus 20:7-8 declar, "Be holy, for I am Jehovah your God, and you shall keep My statutes and do them"; and this is how God's people sanctify themselves — becoming holy as God is holy (I Peter 1:15-16)...
or imitating His perfection (Matt. 5:48, in the context of the law's demands).
The Old Testament teaches that the law of God is perfect (Ps. 19:7), being holy, just, and good like God (Deut. 12:28; Neh. 9:13), and the New Testament viewpoint is the same: the law is perfect (Jas. 1:25), holy, just, and good (Rom. 7:12).
It is a reflection of His character, and the means by which we know Him and His character, righteousness, just, holy, ect..
BY THE WAY.. I took that from Reformed-Theology.org.. from "Bible Ethics"

, from the subsection titled "(B) The principles of God's law are perpetual because they reflect the character of God, who is unchanging."

From ReformedAnswers.org (Is God Under His Own Law):
From J.I Packers Concise Theology: A Guide to Historic Christian Beliefs; under section "God Revealed As Redeemer"; Subsection "Law", second paragraph -
... God's moral law is abundantly set forth in Scripture, the Decalogue (the Tem Commandments), other Mosaic statutes, sermons by the prophets, the teaching of Jesus, and the New Testament letters. It reflects His Holy Character and His purposes for created human beings...
Under the next subsection "Law In Action"; subtitled "God's Moral Law Has 3 Purposes"; second paragraph..
Its first function [
the Law] is to be a mirror reflecting to us both the perfect righteousness of God and our own sinfulness and shortcomings...

Even R.C. Sproul attest to my statement in his piece; "The Goodness of the Law" as seen
here
Funny enough.. all these and MANY MANY more are Reformed in their theology, and are quite well schooled in theology proper and ALL agree with what I was saying.
