Mark 9:21-23

Darby Translation

²¹ And he asked his father, How long a time is it that it has been like this with him? And he said, From childhood;

²² and often it has cast him both into fire and into waters that it might destroy him: but if thou couldst [do] anything, be moved with pity on us, and help us.

²³ And Jesus said to him, The 'if thou couldst' is [if thou couldst] believe: all things are possible to him that believes.
