I Believe; Help My Unbelief (Sermon on Mark 9: 14--29)

It is horrifying for any parent to consider. Your child is sick. Worse than that: Your child is actually possessed by a demon, an evil spirit. It controls his behavior. It tries to kill him. The parent who approached Jesus in today’s Gospel lesson was living every parent’s worst nightmare. Something’s terribly wrong with my child and I’m powerless to do anything about it.
The father of the possessed boy speaks up and reaches out to Jesus. He’s heard the miracle stories; he fumbles for words as he formulates his request: “If you can do anything, have compassion on us and help us.” Jesus replies: “If you can? All things are possible for one who believes.” And in that moment the boy’s father, desperately battling his own doubts and fears, says just about the most honest thing a human being ever says in the Bible; he says: “I believe; help my unbelief.” There was something Jesus responded to in that wrestling, awkward, transparent request—and he honors it. He does what his disciples could not—he extracts the demon from the boy; he gives the boy and his family a new life to live. Through Jesus, God is putting His broken creation together again one person and one family at a time.
“I believe; help my unbelief.” What a simple way to describe the war that goes on in our hearts and minds. It is a classic Christian paradox. We believe and we disbelieve. We trust and we trust no one. We build on the Rock and we build on sand. That’s us. And it’s not necessarily bad news. Well, unbelief is bad, but a spiritual struggle—an inner tension—is proof that faith is fighting for life. Faith that is gasping for breath is still faith; the thing we ought to really fear is no struggle—the fool’s gold of disbelief and the ethic of service to myself as the highest good.
In other words, to have faith in Jesus is to experience spiritual turbulence, because faith that trusts in God goes to war with the sinful self, and the sinful self doesn’t appreciate being fought against. It hates being exorcised. Only Jesus can cast out our sinful nature and fill us with something far better. And as I said, spiritual turbulence is better than no spiritual turbulence. Spiritual turbulence means that faith, which the Holy Spirit gave me through the gospel of Jesus and baptism, is alive and is beating down my sinful impulses. A complete lack of spiritual turbulence means I’m spiritually dead. It means I’m foolishly confident in myself, or I just don’t care about the things of God at all. Both those ways lead to destruction and finally separation from God.
“So Pastor, what you’re saying is that we either live with spiritual turbulence, or die eternally? Sounds pretty hopeless.” And I agree with you. That would be a bleak outlook on life. Let me suggest there is an upside to experiencing spiritual turbulence; the times when your struggling faith is nurtured, fed, and strengthened by a word from God. When we admit to our double-mindedness—“I believe; help my unbelief,” we are confessing sin, and when we confess sin, well, you know what God promises: “If we confess our sins, God, who is faithful and just, will forgive our sins and cleanse us from all unrighteousness.” Jesus is quick to apply his mercy to our doubts. He is quick to forgive us our lack of trust; the prayer “help my unbelief” is one that it pleases Him to answer. But how? How can the Lord help our unbelief? The answer is elegantly simple. He wants to talk to you. Listen to these words from Isaiah, and imagine that it is Jesus speaking these words. It really is; he is the servant speaking in chapter 50. He says: “The Lord God has given me the tongue of those who are taught, that I may know how to sustain with a word him who is weary.” Here’s a slightly different translation: “The Lord God gives me the speech of the learned, so that I know how to talk to encourage the weary.” The encouragement and the knowledge that we need are found in the words of Jesus. The Word of God is the thing that is going to sustain our faith and keep it vital. Holy Scripture gives us the prequel to Jesus’ arrival; the main event of Jesus’ rescue mission to earth; and the sequels, where his followers take His good news into the surrounding world. The Holy Spirit breathes life into us through this story of Jesus! The Word of God is the antidote to fear, doubt, and worry. The Word of God replaces those things with peace, trust, and faith. The Word presents Jesus to us, inviting us to trust in Him not only for eternal life in the future, but also for the forgiveness of sins and help in our battles today.Kind of appropriate, then, that we find ourselves at another Rally Day, with the idea being that we rally around the Word of God and make it a priority. Here’s another place where it would be right to pray: “I believe; help my unbelief.” We might very well pray, “Lord, I believe that it is important to study your Word; help my unbelief that finds all kinds of way to prevent that from happening.” There are plenty of excuses for not being in the Word—I’m not going to go through them all, because we know what they are, and we know they are excuses, not reasons. Will we really rally around the Word of God on this Rally Day? Will we as individuals—as families—as disciples of Jesus—make learning the Word our top priority in the months to come? Will we as a congregation allow Jesus to speak to us in His own words? There’s an awful lot at stake, as our gospel lesson makes abundantly clear. Evil is real. The devil wants you to be his possession. He wants our children, too. And the stark reality is that you’re either Satan’s slave or God’s dearly loved child. There’s no neutral space. We’re either filling ourselves and our children with poison or purity; garbage or grace. We can fill ourselves and our children with junk that kills faith, or holy things that cause faith to grow deeper roots and stronger shoots. May the Holy Spirit inspire each of us to listen to the encouraging Words of our Lord Jesus. If you’re not doing that at all, make a fresh start. If you’re doing a little, push past that and do more. And let’s see what happens when we really listen to and act on the words of our Lord Jesus Christ!
