A chief emphasis is placed upon this perfection of God: God is oftener styled Holy than almighty, and set forth by this part of His dignity more than by any other. This is more fixed on as an epithet to His name than any other. You never find it expressed ‘His mighty name’ or ‘His wise name,’ but His great name, and most of all, His holy name. This is the greatest title of honour; in this latter doth the majesty and venerableness of His name appear (S. Charnock).
As it seems to challenge an excellency above all His other perfections, so it is the glory of all the rest; as it is the glory of the Godhead, so it is the glory of every perfection in the Godhead; as His power is the strength of them, so His holiness is the beauty of them; as all would be weak without almightiness to back them, so all would be uncomely without holiness to adorn them. Should this be sullied, all the rest would lose their honour; as at the same instant the sun should lose its light, it would lose its heat, its strength, its generative and quickening virtue. As sincerity is the luster of every grace in a Christian, so is purity the splendor of every attribute in the Godhead. His justice is a holy justice, His wisdom a holy wisdom, His arm of power a "holy arm" (Ps. 98:1), His truth or promise a "holy promise" (Ps. 105:42). His name, which signifies all His attributes in conjunction, "is holy," Psalm 103:1 (S. Charnock).
Not all the vials of judgment that have or shall be poured out upon the wicked world, nor the flaming furnace of a sinner’s conscience, nor the irreversible sentence pronounced against the rebellious demons, nor the groans of the damned creatures, give such a demonstration of God’s hatred of sin, as the wrath of God let loose upon His Son. Never did Divine holiness appear more beautiful and lovely than at the time our Saviour’s countenance was most marred in the midst of His dying groans. This Himself acknowledges in Psa. 22. When God had turned His smiling face from Him, and thrust His sharp knife into His heart, which forced that terrible cry from Him, "My God, My God, why hast Thou forsaken Me?" He adores this perfection—"Thou art holy," v. 3 (S. Charnock).
This is the prime way of honoring God. We do not so glorify God by elevated admiration, or eloquent expressions, or pompous services of Him, as when we aspire to a conversing with Him with unstained spirits, end live to Him in living like Him (S. Charnock).
