1:12-17 The apostle knew that he would justly have perished, if the Lord had been extreme to mark what was amiss; and also if his grace and mercy had not been abundant to him when dead in sin, working faith and love to Christ in his heart. This is a faithful saying; these are true and faithful words, which may be depended on, That the Son of God came into the world, willingly and purposely to save sinners. No man, with Paul's example before him, can question the love and power of Christ to save him, if he really desires to trust in him as the Son of God, who once died on the cross, and now reigns upon the throne of glory, to save all that come to God through him. Let us then admire and praise the grace of God our Saviour; and ascribe to the Father, Son, and Holy Ghost, three Persons in the unity of the Godhead, the glory of all done in, by, and for us.
17. A suitable conclusion to the beautifully simple enunciation of the Gospel, of which his own history is a living sample or pattern. It is from the experimental sense of grace that the doxology flows [Bengel].
the King, eternal—literally, "King of the (eternal) ages." The Septuagint translates Ex 15:18, "The Lord shall reign for ages and beyond them." Ps 145:13, Margin, "Thy kingdom is an everlasting kingdom," literally, "a kingdom of all ages." The "life everlasting" (1Ti 1:16) suggested here "the King eternal," or everlasting. It answers also to "for ever and ever" at the close, literally, "to the ages of the ages" (the countless succession of ages made up of ages).
immortal—The oldest manuscripts read, "incorruptible." The Vulgate, however, and one very old manuscript read as English Version (Ro 1:23).
invisible—(1Ti 6:16; Ex 33:20; Joh 1:18; Col 1:15; Heb 11:27).
the only wise God—The oldest manuscripts omit "wise," which probably crept in from Ro 16:27, where it is more appropriate to the context than here (compare Jude 25). "The only Potentate" (1Ti 6:15; Ps 86:10; Joh 5:44).
for ever, &c.—See note, above. The thought of eternity (terrible as it is to unbelievers) is delightful to those assured of grace (1Ti 1:16) [Bengel].
