What does Mark 9:24 mean?

This is one of the most poignant verses in the Bible, and the sentiment is shared by believers around the world and throughout history. Jesus has just told a desperate father that his son can be healed if he believes. In a display of beautiful vulnerability, the father submits what faith he has alongside his doubt and fear. He is our example of someone who understands God wants all of us, not just the holiness of the Pharisees (Matthew 5:20), or the bold confidence of the Syrophoenician woman (Mark 7:24–30), or the adoration of Mary of Bethany (John 12:3). He also wants the limitations of Peter (John 21:15–19), the terrible miscalculations of Paul (1 Timothy 1:13), and whatever else we have to give, good or bad.

"Help" is from the Greek root word boetheo and means to bring aid to or comfort. The man may not have an advanced education in the power and faithfulness of God, but he knows what it is to be a father. As he would do anything he can for his son, he trusts that Jesus will do what He can for both his son and his own faith. He may not understand Jesus' power and authority, but he trusts Jesus' heart is like that of a loving father.
