Our fathers ate the manna in the wilderness. As it is written, 'He gave them bread out of heaven{Greek and Hebrew use the same word for "heaven", "the heavens", "the sky", and "the air".} to eat.'"

 It is so with Jesus. So long as he remains a figure in a book he is external to us; but when he enters into our hearts we can feed upon the life and the strength and the dynamic vitality that he gives to us. Jesus said that we must drink his blood. He is saying: "You must stop thinking of me as a subject for theological debate; you must take me into you, and you must come into me; and then you will have real life." That is what Jesus meant when he spoke about us abiding in him and himself abiding in us.
