He is completely separate from His creation. He is morally perfect.

Holiness is perhaps the most important moral attribute of God. It is the only one raised to the superlative level in the Scripture. The Word of God often repeats a word to emphasize its importance. It declares God is holy, holy, holy.

And one called to another and said: “Holy, holy, holy is the Lord of hosts; the whole earth is full of his glory!” (Isaiah 6:3).

And the four living creatures, each of them with six wings, are full of eyes all around and within, and day and night they never cease to say, “Holy, holy, holy, is the Lord God Almighty, who was and is and is to come!” (Revelation 4:8).

Holiness refers to God’s otherness. He is completely separate and infinitely above His creation. “For My thoughts are not your thoughts, nor are your ways My ways,” says the Lord. “For as the heavens are higher than the earth, so are My ways higher than your ways, and My thoughts than your thoughts” (Isaiah 55:8-9).

God is infinitely above man. While it may be said creation (especially man) is like God, it may not be said that God is like man. He, as Creator, vastly differs from man; more than man from the simplest one-celled organism. He is far above us in His being and His ways. He surpasses our understanding. If not, He would not be God. A god that can be completely understood is not a god at all.

Oh, the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments and His ways past finding out! “For who has known the mind of the Lord? Or who has become His counselor?” “Or who has first given to Him and it shall be repaid to him?” For of Him and through Him and to Him are all things, to whom be glory forever. Amen (Romans 11:33-36).

God deserves all glory because:

All things are of Him – He is Creator of all.

All things are through Him – He is Sustainer of all.

All things are to Him – He is Ruler of all.

He is separate, He is holy.

Holiness also refers to God’s moral perfection. He is holy, morally perfect, and all He does is perfect. The holiness of God governs all He does. He is holy in judgment and in mercy; holy in love and anger; in wrath and patience.

Because of His perfection, we should not question anything He does. We should accept that He in His Holy wisdom and love will do what is best for all of creation, including us. We may not understand what He does or why He does it, but we can trust He is right because He is holy.

As we acknowledge His holiness and live before Him in faith, He calls us to be holy.

Because it is written, “Be holy, for I am holy” (1 Peter 1:16). Here holiness refers to being set apart. Because God is holy, He calls us to be set apart to Him. Although we are not morally perfect, God empowers us to live a life that reflects His holiness through the power of the Spirit. Although we are not naturally good like God, He changes us to be like Him by His Spirit who indwells us. He enables us to be holy, as He is holy.

As we recognize God’s holiness and allow ourselves to be made holy through Him, our proper response is worship.

Let us cry with the seraphim, “Holy, holy, holy is the Lord God Almighty.” And proclaim, “Who is like you, O Lord, among the gods? Who is like you, majestic in holiness, awesome in glorious deeds, doing wonders?” (Exodus 15:11).
