16:25-27 That which establishes souls, is, the plain preaching of Jesus Christ. Our redemption and salvation by our Lord Jesus Christ, are, without controversy, a great mystery of godliness. And yet, blessed be God, there is as much of this mystery made plain as will bring us to heaven, if we do not wilfully neglect so great salvation. Life and immortality are brought to light by the gospel, and the Sun of Righteousness is risen on the world. The Scriptures of the prophets, what they left in writing, is not only made plain in itself, but by it this mystery is made known to all nations. Christ is salvation to all nations. And the gospel is revealed, not to be talked of and disputed about, but to be submitted to. The obedience of faith is that obedience which is paid to the word of faith, and which comes by the grace of faith. All the glory that passes from fallen man to God, so as to be accepted of him, must go through the Lord Jesus, in whom alone our persons and doings are, or can be, pleasing to God. Of his righteousness we must make mention, even of his only; who, as he is the Mediator of all our prayers, so he is, and will be, to eternity, the Mediator of all our praises. Remembering that we are called to the obedience of faith, and that every degree of wisdom is from the only wise God, we should, by word and deed, render glory to him through Jesus Christ; that so the grace of our Lord Jesus Christ may be with us for ever.
