But we have no evidence that Jesus currently says or does anything. The Bible wasn't even written by him. It was written by men who wrote down what he allegedly did - and on almost every page is a claim of something that is completely implausible. So trusting "Jesus" fails any analogy to trusting a real living person as well.
Which prophecies?
That doesn't make sense, RS. Why would you think you only need to read one book full of implausible claims to learn the history of Israel? Wouldn't it behoove you to look outside the book at the actual evidence of history, and what else is written, to figure out whether the claims of the book you're reading match reality?
The majority of humans on Earth deny that it's reality, so that is manifestly untrue.
Do you mean the modern secular nation-state of Israel?
Ok, let's look at some of the prophecies to the coming of the Messiah, written in the Tanakh, which I believe to be about Jesus Christ.
Here are some that refer to the first advent:

Take a good look at them and you will see that they relate to many details in the life of Jesus Christ. Are you trying to tell me that the New Testament was 'made up' to fit with the prophecies that had, for hundreds of years, sat unfulfilled in the Hebrew scriptures? Do you realise what would be involved to pull off such a deception?
What exactly do you believe can be trusted as history? Was Josephus a reliable source? Was Tacitus a reliable source? Why do you not trust the New Testament, when the people who gave testimony to the events were clearly present at the time?
I believe the Bible to be the perfect source of evidence for God. The integrity of the book is determined by its inner structure, consistency, coherence and truth. That is why it is possible to argue a case from the scriptures without contradiction.
Evidence that Jesus Christ is alive and well is derived from the life of the Church, which exists as the body of Christ on earth.
