^^^Yes, it does seem that if Jesus was god and wanted people to know that, he would not be coy about it! None of this vague, "I am sent by my father" stuff that could mean just about anything you want. Sent by his bio dad Joseph? Sent by Zeus? Satan? Marlon Brando? The pope? Big Daddy V?
Not to mention, Jesus the all-powerful, all-knowing and all-caring god-being would be able to communicate far, far more clearly than any normal mortal human ever. He would also make sure his message--the most important information ever in the history of the world, right?-- got to everyone on the planet immediately and would never be corrupted or mistaken. Everyone from the people of the Pacific Islands to the Alaskan Inuit to the Mbuti pygmies to the Aztec of Mexico to the Norse Vikings would get the message, all at the same time and in their own languages. No need to wait centuries or millennia for humans to show up with whatever mistranslated version of Jesus' message they happened to bring with them.
What possible downside could there be in that?
Suffice to say, Jesus would probably not rely on fallible people accurately remembering what he said, and then telling other people, who then would tell other people, and so on, in the world's longest game of telephone line, until some time later somebody would think of writing it down. Relying on humans writing stuff down is the kind of thing that ordinary human beings do. That is exactly what Confucius, Muhammed and Joseph Smith did. Why would the one real god do the exact same things as every regular old human philosopher-- and the same as every fake prophet? And most other religions got their stuff written down while the person who came up with the ideas was still alive, ie much closer to the source than the words attributed to Jesus.
By waiting so long, what finally got written down would be the last version of the message, which would be nothing like the original words Jesus said. Even the most simple example of information transmission gets garbled as time passes. Why didn't Jesus write the message himself, in permanent letters of blazing fiery gold on the side of a huge mountain or other landmark on every continent, in every language that would ever be used by humans? Should be child's play for someone who created the entire universe with his voice.
I know what believers will say.
The very idea of Jesus doing something like that is ridiculous, you arrogant atheist. If he did that, you would still not believe, because you want to sin. And if he had done that, there would be decent evidence and thus no need for faith, which is, of course not at all blind although it depends on believing things without decent evidence. If Jesus had done that, everyone would have an equal chance to understand his message accurately, and you cannot have that. Finally, Jesus could not know what languages would be spoken in the future, or how to make the letters permanent, or what message would be the most important one to pass down through all time.
Because to do all that, he would have had to have been, like, a god or something.
