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, (5:18.) It is a day of darkness and gloominess, [1] not of light; of sorrow, not of joy; of destruction, not of salvation. On the other hand, Zechariah (9:9) bids the daughter of Zion rejoice on account of the coming of her King; and justly, for--as 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.

Footnotes

1 - Our author -- quoting from memory, as he frequently does -- appears to have incorporated the words of the prophet Amos, (5:18,) To what end is it for you? the day of the Lord is darkness, and not light, with a parallel passage in Joel, (2:1, 2) for the day of the Lord cometh, for it is nigh at hand; a day of darkness and of gloominess, a day of clouds and thick darkness. -- Ed.

Your redemption draweth nigh - See the notes at Matthew 24:33. This is expressed in Luke 21:31 thus: "the kingdom of God is nigh at hand" - that is, from that time God will signally build up his kingdom. It shall be fully established when the Jewish policy shall come to an end; when the temple shall be destroyed, and the Jews scattered abroad. Then the power of the Jews shall be at an end; they shall no longer be able to persecute you, and you shall be completely delivered from all these trials and calamities in Judea.

And when these things begin to come to pass,.... When the first of these signs appears, or any one of them:
then look up and lift up your heads; be cheerful and pleasant; do not hang down your heads as bulrushes, but erect them, and put on a cheerful countenance, and look upwards, from whence your help comes; and look out wistfully and intently, for your salvation and deliverance:
for your redemption draweth nigh; not the redemption of their souls from sin, Satan, the law, the world, death, and hell; for that was to be obtained, and was obtained, before any of these signs took place; nor the redemption of their bodies at the last day, in the resurrection, called the day of redemption; for this respects something that was to be, in the present age and generation; see Luke 21:32 but the deliverance of the apostles and other Christians, from the persecutions of the Jews, which were very violent, and held till these times, and then they were freed from them: or by redemption is meant, the Redeemer, the son of man, who shall now come in power and glory, to destroy the Jews, and deliver his people; and so the Ethiopic version renders it, "for he draws nigh who shall save you".

redemption--from the oppression of ecclesiastical despotism and legal bondage by the total subversion of the Jewish state and the firm establishment of the evangelical kingdom (Luke 21:31). But the words are of far wider and more precious import. Matthew (Matthew 24:30) says, "And then shall appear the sign of the Son of man in heaven," evidently something distinct from Himself, mentioned immediately after. What this was intended to mean, interpreters are not agreed. But as before Christ came to destroy Jerusalem, some appalling portents were seen in the air, so before His personal appearing it is likely that something analogous will be witnessed, though of what nature it is vain to conjecture.

Now when these things - Mentioned Luke 21:8, Luke 21:10, &c, begin to come to pass, look up with firm faith, and lift up your heads with joy: for your redemption out of many troubles draweth nigh, by God's destroying your implacable enemies.
