John 4:22-24, 34

Ye worship ye know not what: we know what we worship: for salvation is of the Jews. But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him. God is a Spirit: and they that worship him must worship him in spirit and in truth.

Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work.
