The Torah Codes and their startling implications is a huge and awesome topic. We will only touch upon it here, then you can explore some of the excellent Internet resources (below) and make your own decision; are the codes meaningless coincidence, or were they planted in the Torah, woven through the text to drop hints to later generations, and to teach us?
But more to the point: Who could have had the genius to have created a Torah that reads as a story, but is also laced with hidden messages about world events & people that would only appear on the world scene thousands of years later? That is what you see in the codes.
Briefly, if the Torah codes show a knowledge of people and world events that would only appear on the world scene hundreds or thousands of years later, that means the "coder" of the Torah codes would have to be knowledgeable about those people and those events, and be able to weave it all into a Torah that reads as a story, but can also be scanned like computer data to reveal coded messages at specified letter-jump intervals (more below).
God could do that, since He is outside of the system of time. He would be aware of people and events that would yet come to the world, and He would be able to create a document like the Torah that reads as a story, but is also able to be scanned like data to reveal coded messages.
When you see the Torah as a God-created and a God-given document, then obviously it would be a teriffic source of information and inspiration to use when planning your Jewish Future.
To put it another way, Torah statements, and the statements of those scholars and mystics who delved deeply into the Torah, previous thought to be mythical, suddenly take on a new excitement and importance.
