Pastor Andrew explores three types of faith in the context of the disciples' failure to cast out a demon from a boy and Jesus' subsequent deliverance. It identifies a perverted faith in the disciples, who relied on their own abilities rather than God, a tiny faith (like a mustard seed) that, when rightly placed in God, can accomplish great things, and a total faith exemplified by the father's desperate plea to Jesus for mercy, trusting Him despite the disciples' failure. The pastor emphasizes that faith is not about its quantity but its object—trusting in Jesus alone—and encourages believers to repent of self-reliance, pray for increased faith, and rely on God's power through prayer and fasting, while urging the unsaved to trust in Christ's finished work for salvation.
