Matthew 17:20 He replied, “Because you have so little faith. Truly I tell you, if you have faith as small as a mustard seed, you can say to this mountain, ‘Move from here to there,’ and it will move. Nothing will be impossible for you.”
The question from the disciples was “why couldn’t we do that?”
Jesus’ response was simple – because you thought it was too difficult, you didn’t believe it could be done!
But Jesus had no problem relying fully on God to take away the evil spirit within the boy. We need to show more faith and belief in God just as Jesus did before all people.
Trust in God, believe in Him and show the rest of the world you really do!
