Compare these two, clear statements from the Bible, written 1500 years apart:

I will raise up for them a prophet like you from among their brothers; I will put my words in his mouth, and he will tell them everything I command him.  –  (Deuteronomy 18:18 – Words of God to Moses, approximately 3500 years ago)

Don’t you believe that I am in the Father, and that the Father is in me? The words I say to you are not just my own. Rather, it is the Father, living in me, who is doing his work.  –  (John 14:10 – Words of Jesus)

And then, this:

In the past God spoke to our forefathers through the prophets at many times and in various ways,  but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom he made the universe.  –  (Hebrews 1:1–2  –  Unknown author, roughly 2000 years ago)

The reason the Bible fits perfectly together, even over the span of a millennium and a half, is because it was inspired by One Eternal Author Who knew what He would do from before the beginning.  His words have therefore been relevant in all ages, including our own.  Knowing that, pay further attention to the rest of what God told Moses about the One in Whom He would put His words:

If anyone does not listen to my words that the prophet speaks in my name, I myself will call him to account.  –  (Deuteronomy 18:19)

Probably a good idea to really listen to Jesus…
