REVELATION – The Truth Made KnownRevelation is not a book that we should be afraid to study, nor is it one that is impossible to understand. We may not know all that the future holds, but we can know the One who holds the future in His hands.Lesson 17 – Revelation 22:1-21As Revelation concludes John speaks of the glorious city of God where the River of the Water of Life, clear as crystal, flows from God's throne and where mankind is able to eat of the Tree of Life once more.
