It is significant that, when the messengers sent by John the Baptist came to Jesus to ask Him: "Are you he who is to come, or shall we look for another?", He answered by referring to the same testimony with which He had begun His teaching at Nazareth: "Go and tell John what it is that you have seen and heard: the blind receive their sight, the lame walk, lepers are cleansed, and the deaf hear, the dead are raised up, the poor have good news preached to them." He then ended with the words: "And blessed is he who takes no offense at me".
Especially through His lifestyle and through His actions, Jesus revealed that love is present in the world in which we live - an effective love, a love that addresses itself to man and embraces everything that makes up his humanity. This love makes itself particularly noticed in contact with suffering, injustice and poverty - in contact with the whole historical "human condition," which in various ways manifests man's limitation and frailty, both physical and moral. It is precisely the mode and sphere in which love manifests itself that in biblical language is called "mercy."
Christ, then, reveals God who is Father, who is "love," as St. John will express it in his first letter; Christ reveals God as "rich in mercy," as we read in St. Paul. This truth is not just the subject of a teaching; it is a reality made present to us by Christ. Making the Father present as love and mercy is, in Christ's own consciousness, the fundamental touchstone of His mission as the Messiah; this is confirmed by the words that He uttered first in the synagogue at Nazareth and later in the presence of His disciples and of John the Baptist's messengers.
