Which in his times he shall shew. — More accurately rendered, which in his own seasons. Here the language of fervid expectation is qualified by words which imply that in St. Paul’s mind then there was no certainty about the period of the “coming of the Lord.” It depended on the unknown and mysterious counsels of the Most High. The impression left upon our minds by the words of this and the preceding verse is that St. Paul had given up all hope of living himself to see the dawn of that awful day, but he deemed it more than probable that his son in the faith would live to witness it. Hence his words to him: “Keep the commandment without spot until the Epiphany of our Lord Jesus Christ.”
Who is the blessed and only Potentate. — The stately and rhythmical doxology with which the solemn charge to Timothy is closed was not improbably taken from a hymn loved by the Ephesian Christians, and often sung in their churches; the words, then, were, likely enough, familiar to Timothy and his people, though now receiving a new and deeper meaning than before. Well might Timothy, as example to the flock of Ephesus, keep “the commandment without spot, unrebukeable” — fearlessly, even though danger and death were presented before him as the sure reward of his faithfulness — for He who in His own times should reveal (show) the Lord Jesus returning to earth in glory, was inconceivably greater and grander than any earthly potentate, king, or lord, before whose little throne Timothy might have to stand and be judged for his faithfulness to the “only Potentate, the King of kings, and Lord of lords.”
Of the first of these sublime titles, God is termed “the blessed,” or the happy, because He is the source of all blessedness and happiness; and the “only Potentate,” in solemn assertion that the Christian’s God was One, and that to none save to Him could this appellation “only Potentate” be applied. Possibly already in Ephesus the teachers of Gnosticism had begun their unhappy work — with their fables of the mighty æons, and their strange Eastern conception of one God the source of good, and another the source of evil.
The King of kings, and Lord of lords. — God is king over those men style kings, and lord over all men call lords here.
