Extreme hair styles can easily lead one into a trap of the Devil also, and cause others to stumble. For example, a young man in the United States was making fine progress in his study of the Bible, and he was moved to share with an experienced Witness in preaching to others about the good things he was learning from the Bible. From early youth he had let his beard grow, and since some in the business community wore beards, he felt that his wearing one in preaching to others would be acceptable generally. But in speaking to a lady he was unable to do more than introduce himself, when she said: "Im sorry, young man, I do not want to become involved in student revolt." No amount of explanation after this sufficed to clear up the misimpression. After the conversation ended with the closing of the door, he asked the experienced Witness what had happened. He was invited to consider his appearance in relation to what he claimed to be, a servant of God. Not wanting to be responsible for even one persons being stumbled so as to miss the way to everlasting life, this new Kingdom publisher shaved off his beard. Would you be willing to do the same or to make similar adjustments if your appearance gave the wrong impression in a certain community?

When Jesus Christ was a man on earth, did he wear a beard?K.A., U.S.A.
Biblical evidence is the most reliable testimony to be found on this question, and a recent careful review of what it says indicates that Jesus did indeed have a beard..
Nevertheless, as already shown, it is apparent that Jesus did wear a beard, and so artistic representations of him in future Watch Tower publications will harmonize with the Scriptural evidence to that effect.
Doubtless the early Christians followed the custom of the time and locality in which they lived, with regard to the wearing of a beard. The Roman custom was beardlessness. Romans converted to Christianity would very likely continue in the Roman custom, while converts from the Jewish community would continue in the Jewish custom of wearing a beard.
Today Christian ministers, like the early Christians, are concerned with neatness and cleanness, but they strive to dress inconspicuously, so that their appearance does not in any way detract from the dignity or the effectiveness of the message they bear. (2 Cor. 6:3, 4) In recent years in many lands a beard or long hair on a man attracts immediate notice and may, in the minds of the majority, classify such a person undesirably with extremists or as rebels against society. Gods ministers want to avoid making any impression that would take attention away from their ministry or hinder anyone from listening to the truth. They know that people are watching true Christians very critically and that to a great extent they judge the entire congregation and the good news by the ministers appearance as a representative of the congregation.
In paradise restored on earth it would not be out of order if men returned to wearing beards, in perfect fashion, like Adam in Eden.
