This belief had survived in early Christianity, although with other symbols.

And I will pray the Father, and he shall give you another Comforter, that he may abide with you forever; Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you. / I will not leave you comfortless: I will come to you. Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also. / At that day ye shalt know that I am in my Father, and ye in me, and I in you.
