GOD has been pleased to make three great revelations of Himself to man: his Works; his Word ; and his Son, and these revelations have been progressive in character. Nature, the Law, the Gospel; a silent material universe, an inspired Book, a living God-man; these are the three great steps that have led from the death and darkness of sin to that knowledge of the true God which is eternal life.
A fourth revelation of God, fuller and more perfect than any, is yet to come. The only begotten Son, who is in the bosom of the Father, who is the brightness of his glory and the express image of his person, who "declared Him” when He came the first time in grace and humiliation, will declare Him yet more fully when He comes a second time in righteousness and in glory. Then the earth will be filled with the knowledge of the Lord, as the waters cover the sea.
