Not the most important question in the world but the Bible does tell us. Plus it is not a matter of opinion but a matter of actual facts.
Before I answer this I will tell you that Jesus had a beard. Did Jesus have a beard all through His ministry? I have no idea and refuse to say simply because the Bible does not say. We do know He had a beard because when He was crucified because the Bible tells us His beard was plucked out.
As for long hair we can rest assured that Jesus never had long hair. Why? Simply because if He did He would have been in violation of the Bible He had written:
Doth not even nature itself teach you, that, if a man have long hair, it is a shame unto him?
But if a woman have long hair, it is a glory to her: for her hair is given her for a covering. 1 Corinthians 11:14-15
Some say the subject is not important. However the above verses are important enough to God that He put it in His word. Next time you see a picture of Jesus with long hair, know you are looking at someone’s imagination that knows little of the Bible. More later as I recall…….
