Jesus rebuked the demon, and it came out of the boy, and he was healed from that moment. Then the disciples came to Jesus in private and asked, “Why couldn’t we drive it out?” He replied, “Because you have so little faith. I tell you the truth, if you have faith as small as a mustard seed, you can say to this mountain, ‘Move from here to there’ and it will move. Nothing will be impossible for you (Jn.17:18-20).
I don’t know about you, but this verse bothers me. Jesus seems to be saying that the smallest amount of faith can move mountains and if we are not moving mountains then our faith is truly microscopic. Rarely do I feel that I am moving mountains, so a bit of condemnation creeps up when I look at this scripture as the standard. The question then becomes whether or not I am understanding this passage correctly.
Without letting myself off the hook for microscopic faith, there is another way to understand this passage. The word that is translated “little faith” typically means a small amount or lack, but it can also be translated as “a short amount of time” or as “brief.” In the context, Jesus may have been telling his disciples that they didn’t sustain their faith long enough. When the demon didn’t come out right away, they quit. Persistence or perseverance is part of faith. In an instant society, we want it now and are prone to give up if something doesn’t happen quickly. I think we can fall prey to that mindset when it comes to prayer, commanding a demon, or declaring healing. Sometimes, in order to move a mountain, we must persist or endure. The mountain may be moved a shovel full at a time instead of all at once.
James highlights this truth when he says, “Consider it pure joy, my brothers, whenever you face trials of many kinds, because you know that the testing of your faith develops perseverance. Perseverance must finish its work so that you may be mature and complete, not lacking anything” (Ja. 1:2-4). Sometimes we think that spiritual maturity and great faith always produce the overnight miracles of healing, provision, breakthrough, and so for. Yet James is clear that the quality of endurance is part of spiritual maturity.
In his letter to the church at Philippi, Paul exhorts them to “contend for the faith” against ongoing opposition. That text has the flavor of contending, wrestling, and engaging in conflict.
In his “sermon on the mount,” Jesus taught us, “Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. For everyone who asks receives; he who seeks finds; and to him who knocks, the door will be opened” (Mt.7:7-8). The verbs in this passage are “present progressive.” They could be translated as keep asking, keep knocking, and keep seeking. After you have kept on, your prayers will be answered.
Our faith then is not always measured by the immediate miracle. Sometimes it is measured by a belief that God is hearing my prayers and storing them up until the movement when they will be answered in a powerful way. Persistence can be the measure of my faith. Even in the context of deliverance, such as the one in which the disciples of Jesus could not cast out the spirit, we may need to go after that spirit more than once, believing that the power and authority that God has given us weakens the devil’s stronghold each time we command and each time we declare the word of God over it. At some point, when we have persevered, the walls of that stronghold will crack and the enemy will flee. We may think that the walls of Jericho came down all at once, but they came down after seven days of establishing authority in the spiritual realm by marching around the city.
Often, the enemy wins by just holding on long enough for us to give up. In those moments, our faith was sufficient in one sense but too brief for the stronghold to fall. We did not endure. Paul’s life and ministry was defined by endurance. He described it with the following words. “We are hard pressed on every side, but not crushed; perplexed, but not in despair; persecuted, but not abandoned; struck down, but not destroyed” (2 Cor.4:8-9). Basically, he said that they kept getting knocked down, but always got up and pressed ahead. Their faith was in the final victory if they kept going.
Whatever you have been asking for, keep contending. Our faith is enough if it is not too brief.
