The manifold wisdom of God dispenses the salvation of human beings by numerous and inscrutable kindnesses…. For when someone believed that the will of Christ alone was enough to cleanse him of his leprosy, he cured him by the mere assent of his will, saying: I will be clean. When someone else begged him to come and raise his dead daughter by laying his hand on her, he entered his house and granted what he was asking for in conformity with his expectations. When another [said]: Only say a word and my servant shall be healed, he restored the weakened limbs to former strength by a word of command, saying: Go, and be it done to you as you have believed.
When others hoped for healing by touching the hem of his garment, he bestowed the gifts of health abundantly. To others he granted healing for their sickness when he was asked. To others he voluntarily offered healing. He encouraged others to hope when he said: Do you wish to be well? To others who were without hope he brought help. He searched out the desires of others before he satisfied their need, saying: What do you wish me to do for you? To another who did not know how to obtain what he desired he kindly showed it when he said: If you believe you shall see the glory of God. So abundantly did he pour forth his healing powers among others that the Evangelist recalls of them: He healed all their sick…. Gods generosity is shaped according to the capacity of human faith.
