Herein we find proof for the Divine inspiration of the Scriptures. The unregenerate do not really believe in the holiness of God. Their conception of His character is altogether one-sided. They fondly hope that His mercy will override everything else. “Thou thoughtest that I was altogether as thyself” (Ps. 50:21) is God’s charge against them. They think only of a “god” patterned after their own evil hearts. Hence their continuance in a course of mad folly. Such is the holiness ascribed to the Divine nature and character in Scripture that it clearly demonstrates their superhuman origin. The character attributed to the “gods” of the ancients and of modern heathendom are the very reverse of that immaculate purity which pertains to the true God. An ineffably holy God, who has the utmost abhorrence of all sin, was never invented by any of Adam’s fallen descendants! The fact is that nothing makes more manifest the terrible depravity of man’s heart and his enmity against the living God than to have set before him One who is infinitely and immutably holy. His own idea of sin is practically limited to what the world calls “crime.” Anything short of that, man palliates as “defects,” “mistakes,” “infirmities,” etc. And even where sin is owned at all, excuses and extenuations are made for it.
The “god” which the vast majority of professing Christians “love,” is looked upon very much like an indulgent old man, who himself has no relish for folly, but leniently winks at the “indiscretions” of youth. But the Word says, “Thou hatest all workers of iniquity “(Ps. 5:5). And again, “God is angry with the wicked every day” (Ps. 7:11). But men refuse to believe in this God, and gnash their teeth when His hatred of sin is faithfully pressed upon their attention. No, sinful man was no more likely to devise a holy God than to create the Lake of fire in which he will be tormented for ever and ever.
