“Teacher, I brought my son to you, for he has a spirit that makes him mute. And whenever it seizes him, it throws him down, and he foams and grinds his teeth and becomes rigid. So I asked your disciples to cast it out, and they were not able.”
And he answered them, “O faithless generation, how long am I to be with you? How long am I to bear with you? Bring him to me.”
This is certainly one of the oddest reactions that Jesus has in the gospels. In other passages the Lord seemed amazed how the disciples reacted with fear at tumultuous storms and their lack of faith concerning the feeding of thousands. In this and those times the Lord seems annoyed that his disciples are still unable to respond in the way that he did.
My thinking is that the Lord is upset not because the disciples were trying to do something that could not do but because they could not do something that he had empowered them to do. This hits to the heart of life for us today. God does not expect us to do things, spiritual or otherwise, that we are not gifted to do but things we are called to do.
Help me Lord to know those things that I am called and gifted to do.. and to do them well.
