The same link between the 'miracle-sign' and faith is confirmed by other negative facts. Let us recall some of them. In Mark's Gospel we read that Jesus in Nazareth "could perform no miracle, but only laid hands on a few sick people and healed them. And he marvelled at their unbelief" (Mk 6:5-6).

We know the gentle rebuke Jesus once addressed to Peter: "Man of little faith, why did you doubt?". This happened when Peter, who at first went boldly on the waves towards Jesus, then by the violence of the wind became afraid and began to sink" (cf. Mt 14:29-31).

5. Jesus emphasises more than once that the miracle he performed is linked to faith. "Your faith has healed you", he says to the woman who had been suffering from haemorrhaging for twelve years and who, when she came up behind him, touched the hem of his cloak and was healed (cf. Mt 9:20-22; Lk 8:48; Mk 5:34).

Similar words Jesus pronounced while healing blind Bartimaeus, who at the exit from Jericho insistently asked for his help, crying out: "Son of David, Jesus, have mercy on me!" (cf. Mk 10, 46-52). According to Mark: "Go, your faith has saved you", Jesus answers him. And Luke specifies the answer: "Have sight again! Your faith has saved you" (Lk 18:42).

He makes an identical statement to the Samaritan healed of leprosy (Lk 17:19). While to two other blind men pleading to regain their sight, Jesus asks: "Do you believe that I can do this?" "Yes, O Lord!" . "Let it be done to you according to your faith" (Mt 9:28-29).

6. Particularly touching is the episode of the Canaanite woman, who did not cease to ask Jesus' help for her daughter "cruelly tormented by a demon". When the Canaanite woman prostrated herself before Jesus to ask him for help, he replied: 'It is not good to take the bread of the children to throw it to the little dogs' (this was a reminder of the ethnic diversity between Israelites and Canaanites, which Jesus, son of David, could not ignore in his practical behaviour, but to which he alluded in a methodological function to provoke faith). And here the woman intuitively comes to an unusual act of faith and humility. She says: 'It is true, Lord . . . but even little dogs eat the crumbs that fall from their masters' table'. Faced with such a humble, gracious and confident word, Jesus replies: 'Woman, truly great is your faith! May it be done to you as you wish" (cf. Mt 15:21-28).

It is an event difficult to forget, especially when one thinks of the countless "Canaanites" of every time, country, colour and social condition, who reach out their hand to ask for understanding and help in their needs!

7. Note how in the Gospel narrative it is continually emphasised that Jesus, when he "sees faith", performs the miracle. This is clearly stated in the case of the paralytic lowered to his feet through the opening in the roof (cf. Mk 2:5; Mt 9:2; Lk 5:20). But the observation can be made in many other cases recorded by the evangelists. The factor of faith is indispensable; but as soon as it occurs, the heart of Jesus is outstretched to fulfil the requests of the needy who turn to him for help with his divine power.

8. Once again we see that, as we said at the beginning, the miracle is a "sign" of God's power and love that saves man in Christ. But because of this, it is at the same time a call to man to faith. It must lead both the one who is miraculously saved and the witnesses of the miracle to believe.

This applies to the apostles themselves, right from the first "sign" given by Jesus in Cana of Galilee: it was then that they "believed in him" (John 2: 11). Then, when the miraculous multiplication of the loaves took place near Capernaum, with which the heralding of the Eucharist is connected, the evangelist notes that "from then on, many of his disciples turned back and no longer went with him", not being able to accept a language that seemed too "harsh" to them. Jesus then asked the Twelve: "Perhaps you also want to leave?". Peter answered, "Lord, to whom shall we go? You have words to eternal life, we have believed and known that you are the Holy One of God" (cf. Jn 6:66-69). The principle of faith is thus fundamental in the relationship with Christ, both as a condition for obtaining the miracle and as the purpose for which it is performed. This is made very clear at the end of John's Gospel, where we read: "Many other signs did Jesus do in the presence of his disciples, but they were not written in this book. These have been written, so that you may believe that Jesus is the Christ, the Son of God, and so that, believing, you may have life in his name" (John 20: 30-31).
