Matthew 16:27

For the Son of man shall come in the glory of his Father - This seems to refer to Daniel 7:13, Daniel 7:14. "Behold, one like the Son of man came - to the ancient of Days - and there was given him dominion, and glory, and a kingdom, that all people, and nations, and languages should serve him." This was the glorious Mediatorial kingdom which Jesus Christ was now about to set up, by the destruction of the Jewish nation and polity, and the diffusion of his Gospel through the whole world. If the words be taken in this sense, the angels or messengers may signify the apostles and their successors in the sacred ministry, preaching the Gospel in the power of the Holy Ghost. It is very likely that the words do not apply to the final judgment, to which they are generally referred; but to the wonderful display of God's grace and power after the day of pentecost.

For the Son of man ... - That is, he will return to judge the world.

He will come in glory the glory of his Father the majesty with which God is accustomed to appear, and which befits God. He will be attended by angels. He will judge all people.

Reward - The word "reward" means recompense. He will deal with them according to their character. The righteous he will reward in heaven with glory and happiness. The wicked he will send to hell, as a reward or recompense for their evil works. This fact, that he will come to judgment, he gives as a reason why we should be willing to deny ourselves and follow him. Even though it should be now attended with contempt and suffering, yet then he will reward his followers for all their shame and sorrow, and receive them to his kingdom. He adds Mark 8:38, that if we are ashamed of him here, he will be ashamed of us there. That is, if we reject and disown him here, he will reject and disown us there.

16:27 For the Son of man shall come - For there is no way to escape the righteous judgment of God.
