Revelation 7:14-17

I said to him, “My lord, you know [the answer].” And he said to me, “These are the people who come out of the great tribulation (persecution), and they have washed their robes and made them white in the blood of the Lamb [because of His atoning sacrifice]. [Gen 49:11; Dan 12:1] For this reason, they are [standing] before the throne of God; and they serve Him [in worship] day and night in His temple; and He who sits on the throne will spread His tabernacle over them and shelter and protect them [with His presence]. [Rev 21:3] They will hunger no longer, nor thirst anymore; nor will the sun beat down on them, nor any [scorching] heat; [Is 49:10; Ps 121:6] for the Lamb who is in the center of the throne will be their Shepherd, and He will guide them to springs of the waters of life; and God will wipe every tear from their eyes [giving them eternal comfort].” [Ps 23:2; Is 25:8; Ezek 34:23; Rev 21:4]
