John 14:20

At that day ye shall know that I am in my Father, and ye in me, and I in you.

More from John 14

Let not your heart be troubled: ye believe in God, believe also in me.

In my Father’s house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.

And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.

And whither I go ye know, and the way ye know.

Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way?
