Jesus says that it is this faith which made him well. The word used here comes from the word sozo, which can also mean ‘to save’. There can be no doubt that this is what is implied here, for he had already been healed. The physical healing he received from Jesus was an immense grace and a foretaste of the complete wholeness and salvation Jesus came to bring him and the other lepers. But it was only a foretaste. Only through faith—a constant living into that healing through obedience, trust and gratitude expressed in worship—could he be made completely well, could he be saved.
