After Jesus had gone indoors, his disciples asked him privately, “Why couldn’t we drive it out?
It is not that the disciples in the above scripture couldn’t drive out the demon from the cruelly possessed boy; they needed help getting it done. They had cast out demons before but these ones were more entrenched and harder to defeat. Jesus explained that in order to cast out certain demons, the disciples would need some additional tools in their spiritual toolbox. Their faith had not been sufficient to get the job done without some added prayer and fasting. This is still true for us today; we face many challenges as Christians that are difficult to get through without a little extra help.
