“He told them, ‘It was because of your little faith. I tell you the truth, if you have faith the size of a mustard seed, you will say to this mountain, “Move from here to there,” and it will move; nothing will be impossible for you.'”
Jesus explains why the apostles were not able to cast out a demon. He uses hyperbole, but his point is clear that with faith they will be able to do everything.
What part of God’s will appears to be impossible to do? How do we develop faith to meet the challenges of God’s will?
