recall his words in the gospel according to st. john , god is a spirit ; i am the way , and the truth , and the life : no man cometh to the father , but by me ; and i will pray the father , and he will give you another comforter , that he may abide with you for ever ; even the spirit of truth ; whom the world can not receive , because it seeth him not , neither knoweth him : but ye know him ; for he dwelleth with you , and will be in you ; at that day ye shall know that i am in my father , and ye in me , and i in you .
