Y entonces vern al Hijo del hombre, que vendr en una nube con potestad y gran gloria.
John Gill's Bible Commentary
Ver. 27. And then shall they see the son of man , etc.] (See Gill on Matthew 24:30).
Matthew Henry Commentary
Verses 5-28 - With much curiosity those about Christ ask as to the time when the great desolation should be. He answers with clearness and fulness, a far as was necessary to teach them their duty; for all knowledge i desirable as far as it is in order to practice. Though spiritual judgements are the most common in gospel times, yet God makes use of temporal judgments also. Christ tells them what hard things they shoul suffer for his name's sake, and encourages them to bear up under their trials, and to go on in their work, notwithstanding the opposition the would meet with. God will stand by you, and own you, and assist you This was remarkably fulfilled after the pouring out of the Spirit, by whom Christ gave his disciples wisdom and utterance. Though we may be losers for Christ, we shall not, we cannot be losers by him, in the end. It is our duty and interest at all times, especially in perilous trying times, to secure the safety of our own souls. It is by Christia patience we keep possession of our own souls, and keep out all thos impressions which would put us out of temper. We may view the prophec before us much as those Old Testament prophecies, which, together with their great object, embrace, or glance at some nearer object of importance to the church. Having given an idea of the times for abou thirty-eight years next to come, Christ shows what all those thing would end in, namely, the destruction of Jerusalem, and the utte dispersion of the Jewish nation; which would be a type and figure of Christ's second coming. The scattered Jews around us preach the trut of Christianity; and prove, that though heaven and earth shall pas away, the words of Jesus shall not pass away. They also remind us to pray for those times when neither the real, nor the spiritual Jerusalem, shall any longer be trodden down by the Gentiles, and when both Jews and Gentiles shall be turned to the Lord. When Christ came to destroy the Jews, he came to redeem the Christians that were persecute and oppressed by them; and then had the churches rest. When he comes to judge the world, he will redeem all that are his from their troubles So fully did the Divine judgements come upon the Jews, that their cit is set as an example before us, to show that sins will not pas unpunished; and that the terrors of the Lord, and his threatening against impenitent sinners, will all come to pass, even as his word wa true, and his wrath great upon Jerusalem.

21:27 {And qen shall they see} (kai tote oyontai). As much as to say that it will be not till qen. Clearly the promise of the second coming of the Son of man in glory here (#Mr 13:26f.; Mt 24:30f.) is pictured as not one certain of immediate realization. The time element is left purposely vague.
