Adam Clarke, on 1Tim 6:15

“Which in his times he shall shew who is the Blessed and only Mighty, the King of kings, and Lord of lords;”

“Which in his times he shall show - Jesus will appear in the most proper time; the time which the infinite God in his wisdom has appointed for the second coming of his Son. The blessed and only Potentate - Δυναστης, Potentate, is applied to secular governors; but none of these can be styled ὁ μακαριος και μονος, the happy and only One; ὁ Βασιλευς των βασιλευοντων, the King of kings, or the King over all kings; and Κυριος των κυριευοντων, the Lord over all lords or rulers. These are titles which could not be given to any mortals. This is made more specific by the verse following.”
