Who's "that man"?
Imagery is not the Word.
It is rather as Satan portraying himself as an angel of light.
Jesus Christ is not a painting.
He is the God the Word,
the Word of God.
And yes,
He shall return when the last lost sheep for whom He died is found.
"Let"?
What does that mean?
I neither "let" nor "don't let".
And I didn't decide anything.
It is God who commanded no religious imagery,
and Christ who said not to follow anyone saying,
Look,
Here is Christ.
There is no visible Christ on earth.
He is physically at the right hand of His Father waiting for all His enemies to be made His footstool.
It is Paul the Apostle who warned that Satan comes as an angel of light.
Pictures are not the Gospel.
The Gospel is the Word,
and Christ Jesus is the Word.
All others are counterfeits used by the enemy to deceive.
