Context Summary
Revelation 3:14–22 is Jesus’ final and most strident message, addressed to the church at Laodicea. We learn from this assessment that the Laodicean church was lukewarm, smug, and self-satisfied. It boasted about its wealth and need of nothing. But the church deceived itself. In terms of its spiritual condition, it was wretched, pitiable, poor, blind, and naked. Jesus urged the church to turn to Him, as He was positioned outside the church, inviting whoever heard His voice to open the door and welcome Him. Laodicea is the only church of seven which receives only criticism, and no positive remarks.
