“God is a Spirit: and they that worship him must worship him in spirit and in truth. The woman saith unto him, I know that Messias cometh, which is called Christ: ...

Jesus saith unto her, I that speak unto thee am he. “

“Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world. Hereby know ye the Spirit of God: ...

”Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world. ...
We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.”
