Then one of the elders addressed me, saying, “Who are these, robed in white, and where have they come from?” I said to him, “Sir, you are the one that knows.” Then he said to me, “These are they who have come out of the great ordeal; they have washed their robes and made them white in the blood of the Lamb. For this reason they are before the throne of God, and worship him day and night within his temple, and the one who is seated on the throne will shelter them. They will hunger no more, and thirst no more; the sun will not strike them, nor any scorching heat; (Revelation 7:13-16, NRSV)
Who are these robed in white?
Those who have washed their clothes in the blood of the Lamb, and are now dazzling white!
They are in a place around the throne, with God and they will never be burnt by the sun or know scorching heat any more. They will also never again know hunger of be thirsty, for they are with God, and will never experience human need again!
When we are fully with God, we will be/are one of those robed in white, washed in the blood of the lamb!
