Revelation 22:17 (ESV)

17 The Spirit and the Bride say, “Come.” And let the one who hears say, “Come.” And let the one who is thirsty come; let the one who desires take the water of life without price.

The weak and timid, who scarcely dare to muster the enthusiastic come! of the Spirit and the Bride, should not feel sidelined. The thirsty and the desiring should act upon their thirst, and so ultimately wash their robes in the redeeming blood of the Saviour of the world.
