“The grace of our Lord Jesus Christ be with you all. Amen.”
King James Version (KJV)
22:20 He that testifieth these things - Even all that is contained in this book. Saith - For the encouragement of the church in all her afflictions. Yea - Answering the call of the Spirit and the bride. I come quickly - To destroy all her enemies, and establish her in a state of perfect and everlasting happiness. The apostle expresses his earnest desire and hope of this, by answering, Amen. Come, Lord Jesus!
