John 8:23-27

And He was saying to them, “You are from below, I am from above; you are of this world, I am not of this world.

Therefore I said to you that you will die in your sins; for unless you believe that I am, you will die in your sins.”

Then they were saying to Him, “Who are You?” Jesus said to them, “What have I even been saying to you from the beginning?

I have many things to say and to judge regarding you, but He who sent Me is true; and the things which I heard from Him, these I say to the world.”

They did not realize that He was speaking to them about the Father.
