2:18 “To the messenger of the church in Thyatira, write: The Son of God, whose eyes are like flames of fire and whose feet are like glowing bronze, says:
“To the messenger of the church in Thyatira, write:
The Son of God,
He saw what was going on in Thyatira. Also see Revelation 1:14.
And he has the power to "stomp" on any offender He wishes. Also see Revelation 1:15.
One of the trades at Thyatira was bronze working. So this view of the speaker may have had a special impact. Furthermore the members at Thyatira are shown that the speaker knows and sees what is going on with Jezebel in their midst.
You can't hide from God!
