"The man believed what Jesus said to him"
The word of God is living and effective, more piercing than any two-edged sword (Heb 4,12). What greatness of power, what wealth of wisdom in the Word of God is shown by these words of the Apostle to those that seek Christ, who is himself the word, the power, and the wisdom of God. In the beginning, this word was with God, coeternal with him; in his time he was revealed to the prophets, proclaimed by them, and received humbly in the faith of his believing people.
We have, therefore, the word in the Father, the word in the mouth, and the word in the heart. The word in the mouth is the expression of the word that is in the Father and also the expression of the word that is in the heart of man. The word in the heart of man is either the understanding of the word or faith in the word or the love of the word when the word is either understood or believed or loved. When these three are united in one heart so that the word of God is at one and the same time understood, believed and loved, then Christ, who is the word of the Father... dwells in the heart by faith. And with wonderful condescension he who is God in the heart of the Father descends even to the heart of men...
This Word of God... is living, and the Father granted to him that he should have life in himself as the Father has life in himself (Jn 5,26). On this account he is not only living, but life; as he says of himself: I am the way, the truth, and the life (Jn 14,6).Because he is life, he lives in such a way that he is able to give life, for as the Father raises the dead and gives them life, so also the Son gives life to whom he will (Jn 5,21).
