Revelation 21:16

Revelation 2: Letters to Ephesus, Smyrna, Pergamos, and Thyatira The Lord dictates letters to four of the seven churches. To Ephesus He commends their labor and patience and their rejection of evil men, but charges that they have left their first love, calling them to repent and do the first works. To Smyrna, suffering tribulation and poverty yet rich, He warns of coming imprisonment and bids them be faithful unto death to receive a crown of life, promising the overcomer shall not be hurt by the second death. To Pergamos, dwelling where Satan's seat is, He commends their holding fast His name but rebukes those holding the doctrine of Balaam and of the Nicolaitans, promising the overcomer hidden manna and a white stone with a new name. To Thyatira He commends their charity and works yet rebukes their suffering the woman Jezebel to teach and seduce His servants, declaring He will cast her into a bed of tribulation and that He searcheth the reins and hearts; the overcomer shall have power over the nations and the morning star. Revelation 3: Letters to Sardis, Philadelphia, and Laodicea The Lord continues to the remaining three churches. To Sardis He declares they have a name that they live but are dead, urging them to be watchful and strengthen the things that remain, yet noting a few who have not defiled their garments who shall walk with Him in white. To Philadelphia, who has kept His word and not denied His name, He sets before them an open door which no man can shut, promising to keep them from the hour of temptation that shall come upon all the world, and that the overcomer shall be a pillar in the temple of God. To Laodicea He rebukes their being lukewarm, neither cold nor hot, so that He will spue them out of His mouth; they think themselves rich and increased with goods, but are wretched, miserable, poor, blind, and naked, and He counsels them to buy of Him gold tried in the fire. He declares that He stands at the door and knocks, and if any man hear His voice and open the door, He will come in to him; the overcomer shall sit with Him in His throne.
