The Bible’s answer
No one knows exactly what Jesus looked like, since his physical appearance is not described in the Bible. This indicates that Jesus’ physical features are not important. However, the Bible does give us some idea of Jesus’ general appearance.
Features: Jesus was a Jew and likely inherited common Semitic traits from his mother. (Hebrews 7:14) It is unlikely that his features were especially distinctive. On one occasion he was able to travel in secret from Galilee to Jerusalem without being recognized. (John 7:10, 11) And he apparently did not stand out even among his closest disciples. Recall that Judas Iscariot had to identify Jesus to the armed crowd that arrested him.—Matthew 26:47-49.
Hair length: It is unlikely that Jesus’ hair was long, because the Bible says that “long hair is a dishonor to a man.”—1 Corinthians 11:14.
Beard: Jesus wore a beard. He followed Jewish law, which prohibited adult males from ‘disfiguring the edges of their beard.’ (Leviticus 19:27; Galatians 4:4) Also, the Bible mentions Jesus’ beard in a prophecy about his suffering.—Isaiah 50:6.
Body: All indications are that Jesus was physically robust. During his ministry, he traveled many miles. (Matthew 9:35) He cleansed the Jewish temple twice, overturning the tables of money changers, and once drove out livestock with a whip. (Luke 19:45, 46; John 2:14, 15) McClintock and Strong’s Cyclopedia states: “The whole evangelical narrative indicates [Jesus’] sound and vigorous bodily health.”—Volume IV, page 884.
Facial expressions: Jesus was warm and compassionate, and his facial expressions no doubt reflected this. (Matthew 11:28, 29) People of all sorts sought him out for comfort and help. (Luke 5:12, 13; 7:37, 38) Even children felt at ease in his presence.—Matthew 19:13-15; Mark 9:35-37.
Misconceptions about Jesus’ appearance
Misconception: Jesus was always somber, melancholy.
Fact: Jesus perfectly reflected the qualities of his heavenly Father, Jehovah, whom the Bible describes as “the happy God.” (1 Timothy 1:11; John 14:9) In fact, Jesus taught others how to be happy. (Matthew 5:3-9; Luke 11:28) These facts indicate that Jesus often reflected happiness in his facial expressions.
