We don’t know what Jesus looks like, and I don’t like to see Him depicted—especially as a baby or on the cross. And I don’t like to see him shown looking like a hippie with long hair.
We know that he does NOT have long hair, though. See I Cor. 11:14.
You read the Apostle Paul, speaking to the Corinth church, about not blending in with the male temple prostitutes (who had long hair) to be relevant to saying Jesus did not have long hair?
