Can You Believe and Doubt at the Same Time

Here is the question in its strongest form. Faith, the New Testament seems to say, is confidence in what we hope for and assurance about what we do not see. Jesus tells people that their faith has healed them, and in Nazareth he could do few miracles because of their unbelief. James says that the one who doubts is like a wave tossed by the wind and should not expect to receive anything from the Lord. Put those together and the conclusion looks unavoidable. Doubt disqualifies. If you are not sure, you are not in. And that leaves a great many honest Christians on the outside, because they are not sure, and they are tired of pretending.

The objection deserves to be taken seriously rather than soothed. It is not a misreading. Scripture really does commend confident faith and really does warn against a divided mind. Any answer that simply says doubt is fine has not read the same Bible.

But the Bible also contains Mark 9. A father brings his son, who has been tormented since childhood. He asks Jesus, if you can, to help. Jesus turns the condition back on him. If you can? Everything is possible for one who believes. And the father says, immediately, I do believe; help me overcome my unbelief.

Then Jesus heals the boy.

Read that slowly, because everything turns on the order. The man confesses faith and unbelief in the same breath. He does not resolve the contradiction. He does not go away to work on his doubt and come back when it is fixed. He presents both to Jesus and asks for help with the second. And Jesus does not say, come back when you are sure. He acts. The healing comes to a man whose faith was, by his own admission, mixed.

So what is the difference between this father and the wave tossed by the wind that James warns about? The difference is where each one is facing. James is describing someone who asks God for wisdom while keeping a foot in each camp, hedging, not really wanting the answer, ready to go another way if the wind changes. That is double-mindedness, and it is closer to insincerity than to honest uncertainty. The father in Mark 9 is not hedging. He has come. He has knelt. He has asked. His doubt is not a refusal to commit; it is the residue of years of disappointment, and he brings it to the only one who can do something about it.

This suggests a working distinction. There is doubt that walks away and doubt that walks toward. The first uses uncertainty as a reason not to come. The second comes anyway, uncertainty and all, and says so. Scripture is hard on the first. It is astonishingly gentle with the second. Thomas doubted and was shown the wounds. John the Baptist, in prison, sent to ask whether Jesus was really the one, and Jesus answered him and then praised him to the crowd. The father in Mark 9 doubted out loud and went home with a healed son.

Notice too that the father's faith was not the power that healed the boy. Jesus was. This matters, because much modern anxiety about doubt comes from a quiet assumption that faith works like a battery, and that if you cannot muster enough, the light stays off. The Gospels do not teach that. They teach that faith is the hand that reaches for Jesus, and a trembling hand can still reach. The healing happens because of who is being reached for, not because of the steadiness of the hand.

There is one more thing in the passage that speaks to doubters, and it is easy to miss. After the healing, the disciples ask why they could not do it, and Jesus says this kind comes out only by prayer. The disciples were not doubting. They were confident, perhaps too confident, and they failed because they had stopped asking. Meanwhile the doubting father, who asked, received. Certainty without dependence did worse than doubt with dependence. That should reorder our fears. The dangerous condition is not uncertainty. It is self-sufficiency.

What does this mean in practice for a believer who is not sure? First, say so, to God, in words. The father's sentence is available to anyone. I believe; help my unbelief. It is not a lesser prayer. It may be the most honest prayer in the Gospels. Second, keep coming. Doubt that stays in the room, in the Scriptures, in the congregation, in prayer, is doubt that is walking toward Jesus, and he has never turned that kind away. Third, stop measuring your faith by its feeling of certainty. Measure it by its direction. Where are your feet pointed on the days you are least sure? If they are still pointed at him, you are the father in Mark 9, and you are in good company.

Can you believe and doubt at the same time? A man did, out loud, in front of a crowd, and Jesus healed his son. The verse is still in the Bible. It was kept there for you.
