CCC 2610

Just as Jesus prays to the Father and gives thanks before receiving his gifts, so he teaches us filial boldness: "Whatever you ask in prayer, believe that you receive it, and you will." Mk 11:24. Such is the power of prayer and of faith that does not doubt: "all things are possible to him who believes." Mk 9:23; cf. Mt 21:22. Jesus is as saddened by the "lack of faith" of his own neighbors and the "little faith" of his own disciples Cf. Mk 6:6; Mt 8:26. as he is struck with admiration at the great faith of the Roman centurion and the Canaanite woman. Cf. Mt 8:10; 15:28.
