25 Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,
English Standard Version
25 Now to him who is able to strengthen you according to my gospel and the preaching of Jesus Christ, according to the revelation of the mystery that was kept secret for long ages
25 All of our praise rises to the One who is strong enough to make you strong, exactly as preached in Jesus Christ, precisely as revealed in the mystery kept secret for so long
New King James Version
25 Now to Him who is able to establish you according to my gospel and the preaching of Jesus Christ, according to the revelation of the mystery kept secret since the world began
New Living Translation
25 Now all glory to God, who is able to make you strong, just as my Good News says. This message about Jesus Christ has revealed his plan for you Gentiles, a plan kept secret from the beginning of time.
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.
