Check for images of Jesus on Google, and the plethora of possibilities is quite pronounced. Each of them, including the photos of actors portraying the Son of Man, is different. There was a certain tendency, however, until modern times, to portray Him as somber and/or soft. Most of the religious imagery until the 20th century falls into this category.
Sadly, our concept of the man is often colored by the images we’ve seen, rather than by the Book we’ve read.
