It is in this state of things,— the state in which man is united with God in wisdom,— that we find the truth of that interesting passage of Scripture, "The secret of the Lord is with them that fear him, and he will show them his covenants." [Ps. 24:14] No longer a God afar off; he assumes a position of friendship and intimacy, and converses with them, as it were, face to face. By secret intimations, which are not the less true for being silent, he explains the doctrines of righteousness, and shows the signs of his coming.
And, we may properly add, it is in this state of things that we find one great ground of encouragement and hope. Knowledge is power even on human principles, and when it is infused more or less with human error. What, then, shall be the power of God's people, when it shall be said of them, in the language of the prophets and of the Saviour, "And they shall all be taught of God" [John 6: 25.] "I will give you a mouth and wisdom," says the Saviour in another place, "which all your adversaries shall not be able to gainsay nor resist." [Luke 21: 15.] True it is that the voice of mere human wisdom, when assuming an adverse position, has but little power against the voice of God speaking from a holy heart. And when the heart of the church shall become holy, so that the voice of the church shall be synonymous with a declaration from the God of the church, then shall the deaf hear and the unbelieving be convinced.
