Rev. 2:1 ¶ “To the angel of the church in Ephesus write: These are the words of him who holds the seven stars in his right hand, who walks among the seven golden lampstands…”
The church at Ephesus has lost something. Each church gets a picture of Jesus, that usually correlates with what they need. Apparently Ephesus needs to know that He walks among them still and whatever was lost can still be found.
