Mark 9:21-24

21Jesus asked his father, “How long has this been happening to him?” And he answered, “Since childhood.

22The demon has often thrown him both into fire and into water, intending to kill him. But if You can do anything, take pity on us and help us!”

23Jesus said to him, “[You say to Me,] ‘If You can?’ All things are possible for the one who believes and trusts [in Me]!”

24Immediately the father of the boy cried out [with a desperate, piercing cry], saying, “I do believe; help [me overcome] my unbelief.”
