And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb. Therefore are they before the throne of God, and serve him day and night in his temple: and he that sitteth on the throne shall dwell among them. They shall hunger no more, neither thirst any more; neither shall the sun light on them, nor any heat. For the Lamb which is in the midst of the throne shall feed them, and shall lead them unto living fountains of waters: and God shall wipe away all tears from their eyes.
Those who are clothed in white robes, serving God around His throne, could have been martyred for Christ. Whether or not they suffered for serving Christ, they received the blessings of: perfect nearness – they are before the throne, perfect service – they serve God day and night, perfect fellowship – the One who sits on the throne dwells among them, perfect satisfaction – they will not longer hunger or thirst, perfect security – they will not be exposed to the elements, perfect guidance – Jesus Himself will lead them, and perfect joy – God will wipe away every tear from their eyes.
