My favorite verse, I think, although that’s a hard choice, in the Bible is from the book of Revelation:
The Spirit and the Bride say, “Come.” And let him who hears say, “Come.” And let him who is thirsty come, let him who desires take the water of life without price. Revelation 22:17
A favorite verse from the whole Bible would be difficult... I did mean just for that Psalm...:)
