The Power of Faith

A19fterward the disciples came to Jesus privately and asked, “Why couldn’t we drive it out?” 20“Because you have so little faith,” He answered. “For truly I tell you, if you have faith the size of a mustard seed, you can say to this mountain, ‘Move from here to there,’ and it will move. Nothing will be impossible for you.”
