God cannot be seen, but He can listened to and spoken to!

In the beginning was the relationship.

One must be truly able to say I in order to know the mystery of the Thou in its whole truth.

The I of the basic word I-Thou is different from that of the basic word I-It.

The salvation of man does not lie in his holding himself far removed from the worldly, but in consecrating it to holy, to divine meaning.

Only men who are capable of saying Thou [an attitude of deep respect] to one another can truly say we with one another.

The basic word I-Thou can be spoken only with one's whole being. The concentration and fusion into a whole being can never be accomplished by me, can never be accomplished without me. I require a Thou to become; becoming I, I say Thou.
