28. Verily, I say to you. As the disciples might still hesitate and inquire when that day would be, our Lord animates them by the immediate assurance, that he will presently give them a proof of his future glory. We know the truth of the common proverb, that to one who is in expectation even speed looks like delay; but never does it hold more true, than when we are told to wait for our salvation till the coming of Christ. To support his disciples in the meantime, our Lord holds out to them, for confirmation, an intermediate period; as much as to say, “If it seem too long to wait for the day of my coming, I will provide against this in good time; for before you come to die, you will see with your eyes that kingdom of God, of which I bid you entertain a confident hope.” This is the natural import of the words; for the notion adopted by some, that they were intended to apply to John, is ridiculous.
Coming in his kingdom. By the coming of the kingdom of God we are to understand the manifestation of heavenly glory, which Christ began to make at his resurrection, and which he afterwards made more fully by sending the Holy Spirit, and by the performance of miracles; for by those beginnings he gave his people a taste of the newness of the heavenly life, when they perceived, by certain and undoubted proofs, that he was sitting at the right hand of the Father.
