Joel 3:21

For I will cleanse their blood that I have not cleansed, namely, through the atonement wrought by the Messiah; for the Lord dwelleth in Zion. The entire description clearly does not speak of a mere earthly, temporal glorification of Jerusalem and a corresponding desolation of Egypt and Edom, but the latter are types of the powers opposing the Church of God, and Jehovah is setting forth the blessings which the work of the Church is bringing to men, on the basis of the redemption brought about by Jesus Christ. Cf Revelation 22:2. The Lord is dwelling in the midst of His Church and revealing Himself as the King of His people, partly by the destruction of His enemies, partly by the perfection of His kingdom in glory.
