1. Revelation 7:14 (ESV)
  2. Exposition

What does it mean that the persons of this multitude have washed their robes in the blood of the Lamb?

Revelation 7:14 (ESV)

14 I said to him, “Sir, you know.” And he said to me, “These are the ones coming out of the great tribulation. They have washed their robes and made them white in the blood of the Lamb.

Being washed in the blood of the Lamb describes the glorious gospel of redemption: sins are washed away. See commentary on Revelation 7:9.
