Luke 21:28

Luke 21:28.And when these things begin to take place. Luke expresses more clearly the consolation by which Christ animates the minds of his followers; for, though this sentence contains nothing different from the words of Matthew, which we have just now explained, yet it shows better for what purpose the angels will come, as we are told, to gather the elect. For it was necessary to contrast the joy of the godly with the general sorrow and distress of the world, and to point out the difference between them and the reprobate, that they might not view with horror the coming of Christ. We know that Scripture, when it speaks not only of the last judgment, but of all the judgments which God executes every day, describes them in a variety of ways, according as the discourse is addressed to believers or to unbelievers.

To what purpose is the day of the Lord to you?
says the prophet Amos, (Amos 5:18.)

It is a day of darkness and gloominess, (154) not of light; of sorrow, not of joy; of destruction, not of salvation. On the other hand, Zechariah (Zechariah 9:9) bids the daughter of Zion rejoice on account of thecoming of her King; and justly, for—as Isaiah (Isaiah 35:4) tells us—the same day which brings wrath and vengeance to the reprobate brings good-will and redemption to believers.

Christ therefore shows that, at his coming, the light of joy will arise on his disciples, that they may rejoice in the approaching salvation, while the wicked are overwhelmed with terror. Accordingly, Paul distinguishes them by this mark, that they wait for the day or coming of the Lord, (1 Corinthians 1:7) for that which is their crown, and perfect happiness, and solace, is delayed till that day, (2 Timothy 4:8.) It is therefore called here (as in Romans 8:23) redemption; because we shall then obtain truly and perfectly the consequences of the deliverance obtained through Christ. Let our ears therefore be awake to the sound of the angel’s trumpet, which will then sound, not only to strike the reprobate with the dread of death, but to arouse the elect to a second life; that is, to call to the enjoyment of life those whom the Lord now quickens by the voice of his Gospel; for it is a sign of infidelity, to be afraid when the Son of God comes in person for our salvation.
