We know that the wisdom of God is foolishness to the world; but we, i.e., believers, must admit that much of scripture is foolishness to us, too. God requires us to be diligent students of his Word, and to rely on this Holy Spirit to quicken our understanding. Charnock wrote:
The whole scheme of godliness is a mystery. No man or angel could imagine how two natures so distant as the Divine and human should be united; how the same person should be criminal and righteous; how a just God should have a satisfaction, and sinful man a justification; how the sin should be punished, and the sinner saved. None could imagine such a way of justification as the apostle in this epistle declares: it was a mystery when hid under the shadows of the law, and a mystery to the prophets when it sounded from their mouths; they searched it, without being able to comprehend it (1 Peter i. 10, 11). If it be a mystery, it is humbly to be submitted to: mysteries surmount human reason. The study of the gospel must not be with a yawning and careless frame. Trades, you call mysteries, are not learned sleeping and nodding: diligence is required; we must be disciples at God’s feet. As it had God for the author, so we must have God for the teacher of it; the contrivance was his, and the illumination of our minds must be from him. As God only manifested the gospel, so he only can open our eyes to see the mysteries of Christ in it.
