1:13 in the midst. Jesus is always “in the midst” of His church, even when only “two or three are gathered together in my name” (Matthew 18:20).
1:13 candlesticks. Compare Exodus 25:31. The candlesticks, here represent His churches, which “shine as lights in the world” (Philippians 2:15).
1:13 down to the foot. Note that there is no nudity, or semi-nudity, in heaven. Both Christ and His saints are always arrayed appropriately (Revelation 19:8,14).
