"Because of this they are before the throne of God and serve Him day and night
We have two robes. One robe, through which we come before God, was put on at salvation. The other robe is the righteousness of our own conduct; it is our victory through which we come before Christ. In Revelation 3:18 the white garment (the second one) requires the paying of a price, but the redemption typified in the former case does not need to be purchased. No Christian will be condemned by God to perdition (John 5:24), but neither will there be a single Christian who will not be judged before the judgment seat of Christ concerning his conduct (2 Cor. 5:10). Their robes were cleansed not because of the great tribulation, but because of the blood of the Lamb. They applied the blood of the Lamb to their robes. This shows that they were contaminated on earth; nevertheless, they practiced 1 John 1:9 all the time so that they were cleansed.
4. Revelation 7:15 "Because of this they are before the throne of God and serve Him day and night in His temple; and He who sits upon the throne will tabernacle over them." "Because." According to the foregoing text, the reason that they can serve God is because they did not take the matter of sin lightly. 5. Revelation 7:16-17 "They will not hunger any more, neither will they thirst any more, neither will the sun beat upon them, nor any heat; for the Lamb who is in the midst of the throne will shepherd them and guide them to springs of waters of life; and God will wipe away every tear from their eyes." Compare this with Isaiah 49:10 (cf. Isa. 49:6; Acts 13:47; Isa 49:8; 2 Cor. 6:2). "They will not hunger any more, neither will they thirst any more" is the fulfillment of hope. "Neither will the sun beat upon them, nor any heat." In the new city, there is no need of the light of the sun or moon (Rev. 21:23; 22:5). It is not that there is no sun or moon, but there is no need to use their light. Yet there is still night on the new earth (21:25); since there is "day," there must be night. "God will wipe away every tear" because there is no need to shed tears anymore. One thing deserves our attention. The people in Revelation 7:9-17 and the manchild in Revelation 12:1-11 have many similarities: (1) Revelation 7:10 says that they were redeemed by the Lamb. Revelation 12:11 says that the man-child overcame because of the blood of the Lamb. (2) Revelation 7:9 says that they are standing before the throne. Revelation 12:5 says that the man-child is caught up to God and to His throne.
