2. Although not always conscious and clear, in the human heart there is a deep longing for God, which St Ignatius of Antioch eloquently expressed as follows: "A living water murmurs in me and says within me: 'Come to the Father!'" (Ad Rom. 7). "Lord, show me your glory", Moses pleads on the mountain (Ex 33:18).
After the Incarnation, there is a face of man in which it is possible to see God. Since then, a new relationship is possible between the Creator and the creature, that of the son with his Father.
By passing on to us the direct testimony of the life of the Son of God, the Gospel of John shows us the way to know the Father. The invocation 'Father' is the secret, the breath, the life of Jesus.
