1. The "miracles and signs" that Jesus performed to confirm his messianic mission and the coming of the kingdom of God are ordered and closely linked to the call to faith. This call in relation to the miracle has two forms: faith precedes the miracle, indeed it is a condition for it to take place; faith constitutes an effect of the miracle, because it is provoked by it in the souls of those who received it, or witnessed it.
It is well known that faith is man's response to the word of divine revelation. The miracle occurs in organic connection with this revealing word of God. It is a 'sign' of his presence and working, a sign, one might say, that is particularly intense. All this sufficiently explains the special link that exists between the "miracle-signs" of Christ and faith: a link so clearly delineated in the Gospels.
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!
