The trouble with mountain top experiences is that you have to descend from the mountain. The situation into which Jesus descended contrasts sharply with what he had experienced on the Mount of Transfiguration, as Mark 9:14–32 records.
You need faith! Jesus grieves over an unbelieving generation. Jesus descends into conflict. A crowd surrounds the remaining disciples and a group of teachers of the law are arguing with them. And at the center of the commotion is a man who has come to the disciples for healing for his son, who was possessed by an evil spirit, but they had been unable to do so. Jesus points out unbelief: The characterization as “unbelieving” and the rhetorical questions of verse 19 are directed towards the crowd, eager to see Jesus work a miracle, even welcoming him, but failing to recognize who he really is, and failing to trust him as the Messiah. To the extent that our society is religious, much of it might well be described similarly by Jesus. We want religion, but we want it on our own terms. We want a God on whom we can depend in times of crisis and need, but trust and commitment are a different matter. The characterization certainly is directed to the teachers of the law, who appear to be present for the purpose of disputing with the disciples. They had criticized Jesus for casting out evil spirits, and were hardly looking at the activity of the disciples in a more favorable light. The words of Jesus describe the skepticism of the desperate father, “If you can do anything….” And the anguished questions are addressed to the disciples. No they were not utterly devoid of faith, they are still followers of Jesus. But their faith is too weak to handle the challenges of the teachers of the law and the unbelief around them. Though they had been given the authority to cast out evil spirits, and had used it (Mark 6:7, 13), their efforts were futile this time. It is as though the disciples can hardly be distinguished from the unbelieving world around them. Similarly we, the people of God, can find ourselves frustrated and seemingly helpless in face of a world in opposition to God. Jesus’ words, especially the contrasting “I” and “you,” recall the Lord’s conflict with his people, their distress becoming his, Isaiah 63:8–10. His cry is one of anguish, while not regretting his messianic work, he does express frustration with the people he has come to redeem. Jesus does not soft-pedal his disappointment. Nor does he allow excuse (such as, after all, we’re only human and we’re dealing with something bigger than we are). The problem that Jesus identifies with his disciples, and often with us, is unbelief.
Jesus’ cry pushes you to ask, on what does my faith depend? The disciples, perhaps because of their earlier success, may have been looking at their own strength and abilities. Jesus was not with the body of disciples when the father came for help — they felt it was up to them, and tried to act in their own strength. They failed to recognize that the authority they had exercised was Christ’s not their own. You and I face different situations (probably none of us are going to be asked to cast out an evil spirit who is causing epileptic-like symptoms), but we face similar temptations to go it alone, to act in our own strength and wisdom. How do you respond when you tensions in your family life? What is your first reaction when a difficult situation comes up at work? What do you do when you face a challenging situation in school? Do you draw first on your experience, on the resources of the world around you? When Jesus challenged the father’s doubt (“if you can”), he recognized his own lack of faith, and asked for Christ’s help in overcoming his unbelief. At the heart of faith is looking outside of yourself to another. That is what Abram does in Genesis 15:6. Though his faith is not flawless (here he is considering making Eliezer his heir, later he and Sarai try to provide the promised child via the relationship with Hagar), ultimately he rests on God’s promise. He believes God, and that placing your trust, not in yourself, but in God, lies at the heart of your Christian faith.
“Faith is man in his weakness trusting God’s promise in his word. Only through such weakness is the strength of God seen…. Jesus’ actions pointed forward to the time when he would conquer all the powers of darkness — in the weakness of the cross and the triumph of his own resurrection.”
Sinclair B. Ferguson, Let’s Study Mark, p. 145

Turn to your faithful Savior for help. Jesus is ultimately the one who believes. In Mark 9:23 Jesus reproves the father’s skeptical “if you can.” He tells him (and us) that all things are possible for him who believes. Faith is sometimes misconstrued as something that we crank up, and when we work it up to a certain level, we receive what we pray for. I have seen the pastorally crippling effect of a faith healer blaming failed healings on lack of faith on the part of the sufferer. Notice the ambiguity in Jesus’ response. He is calling the father to greater faith, to overcome his doubt — and the father responds appropriately. Certainly Jesus is calling each of us to more faithful trust in him. But in speaking of the one who believes, Jesus appears to be speaking ultimately of himself. You and I trust in Christ for the forgiveness of our sins. He never sinned, and does not need faith in that way. Yet, he is the believing One, entrusting himself to his Father in heaven, as he walks the road to Jerusalem to suffer and die. He is the believing one, who contrasts himself with the unbelieving generation. He is the sin-bearer, and he is trusting his Father in heaven to vindicate him as he faithfully does his work. Jesus is not just encouraging the father and the disciples to fan the embers of faith a bit, to raise the level of their faith thermometer a little. Rather, he is inviting, he is commanding his audience there, and you and me, to entrust ourselves to him. He is the One who believes. Nor is he simply holding out his faith as an example to motivate us. Rather, he, by faith, is providing himself as the sin-bearer, undergoing the curse for his people. Notice that God strengthens Abram’s faith in Genesis 15 by that strange vision of the burning torch passing between the cut animals. As Jeremiah 34:18 indicates, that is God taking the curse of the covenant upon himself. As Jesus goes to the cross (this incident is bracketed by references to the death and resurrection) he is the reality of what Abram was given in a vision. In his own trust in the Father, Jesus has the authority to cast out the evil spirit (notice his claim to absolute authority), commanding it never to return. The convulsing attack as the spirit departs leaves the boy appearing (though not really) dead. And in actions and words that recall his raising the daughter of Jairus, Jesus takes his hand and commands him to rise. The resurrection power of the Lord is brought to bear in this situation that anticipates his own passage through death into new power. As you entrust yourself to your faithful Savior, be assured that his power and grace are with you in whatever you face this week. Our prayers may not always be answered in exactly the way we expect and hope, but the Lord will be with you, giving you the grace and the strength to face each of those situations (family tensions, problems at work, difficulty in school).
“True faith, in short, is the great benefit of the covenant of grace by which we are incorporated into Christ and accept him with all his benefits. Just as the offer of the grace of God in Christ must be preached to all, so it may be accepted by all with a childlike faith.”
“This certainty, which relates both to the objective grace of God in Christ, and to the believer’s subjective participation in it, is not an external additive to faith but is in principle integral to it from the start. It is not obtained by looking at ourselves but by looking away from ourselves to Christ. It is grounded in the promises of God, not in changing experiences or imperfect good works. Doubts and fears do certainly arise from time to time in the believer’s heart (Matt. 8:25; 14:30; Mark 9:24), and believers must fight against them throughout their lives. However, they can only wage that struggle and only prevail in that struggle by the power of the faith that holds on to God’s promise, rests in the completed work of Christ, and is thus by nature, certain.”

Ask God to help your unbelief. The father of the boy gets it right in his cry to Jesus, “I do believe, help me overcome my unbelief.” He knows he is speaking to the right person. Like the Psalms, which sometimes bang on the gates of heaven, crying out for God to hear and answer, the focus is on God. Keep this father’s prayer in mind as you come to the Lord’s Table today (and other days). Self-examination is something we need to do — but it is not primarily making sure that our faith is up to a certain level at which we may safely come to the Lord’s Table. It’s not that we check things off (I haven’t gossiped all week, so I can partake). Rather, it is a matter of recognizing the body of Christ, first in the most basic sense (am I trusting in Christ, am I baptized into him, am I part of Christ’s body?), and then in the related sense, where the Corinthians seemed to fall so short (do I recognize that God’s people are his body and am I living as part of that body?). As you repent of your sins, including the sin of unbelief, as you cry, I believe, help my unbelief, Christ invites you as a repentant sinner to come to him and be fed. The disciples took advantage of the privacy of a house to ask Jesus why they had failed in casting out this evil spirit. Jesus points them to the need for prayer. (“Fasting” is missing from some of the older manuscripts, and may not have been something Jesus said here. If it is original, he means fasting as it is part of a life of prayer — not as the Pharisees made it, an effort at self-righteousness.) Prayer at its heart involves faith, turning from trusting yourself to the power and faithfulness of your Savior. Prayer is crucial to walking by faith, not by sight, 2 Corinthians 5:7.
Believing in Christ is not only a mountain-top experience of coming to trust him for the first time. It is also living your daily life, not only your quiet time and prayer life, but also the big and little decisions you make, not in your own strength and wisdom, but recognizing your own weakness and resting on the faithfulness and power of your Savior.
