Therefore are they before the throne of God - The reason why they are there is to be traced to the fact that the Lamb shed his blood to make expiation for sin. No other reason can be given why anyone of the human race is in heaven; and that is reason enough why any of that race are there.
And serve him day and night in his temple - That is, continually or constantly. Day and night constitute the whole of time, and this expression, therefore, denotes constant and uninterrupted service. On earth, toil is suspended by the return of night, and the service of God is intermitted by the necessity of rest; in heaven, as there will be no weariness, there will be no need of intermission, and the service of God, varied doubtless to meet the state of the mind, will be continued forever. The phrase, “to serve him in his temple,” refers undoubtedly to heaven, regarded as the temple or holy dwelling-place of God. See the notes on Revelation 1:6.
And he that sitteth on the throne - God. See the notes at Revelation 4:2.
Shall dwell among them - σκηνώσει skēnōsei. This word properly means, “to tent, to pitch a tent”; and, in the New Testament, to dwell as in tents. The meaning here is, that God would dwell among them as in a tent, or would have his abode with them. Perhaps the allusion is to the tabernacle in the wilderness. That was regarded as the special dwelling-place of God, and that always occupied a central place among the tribes of Israel. So in heaven there will be the consciousness always that God dwells there among his people, and that the redeemed are gathered around him in his own house. Prof. Stuart renders this, it seems to me, with less beauty and propriety, “will spread his tent over them,” as meaning that he would receive them into intimate connection and union with him, and offer them his protection. Compare Revelation 21:3.
