If it would have been of benefit the Lord would have included it.
If a person reads the Sira, the official Islamic biography of Mohammed’s entire life from cradle to grave. One might get an idea of what elements the life of a young man in the Middle East might contain. With the exception that Jesus was a carpenter. And there was no Roman occupation at that time.
And the difference that here was the Savior, God incarnate, and He would have acted that way. We err to dumb down our ideas of Jesus’ ministry just by living, just because the bible never bothered to spell it out.
And anyhow, in a “general” way it WAS included, in John’s concluding comment. If we lack the “sanctified imagination” to see how the character that God wishes to imbue humanity with (as opposed to the one it chose in Eden) might play out in various scenarios, then we could stand to ask the Lord to let us “dream dreams and see visions.”
