The mustard tree is a fascinating plant. Its tiny seed is one of the smallest in the world, and must be collected by soaking the pit of the mustard fruit for several days and then straining the resulting pulp through a cloth. The seed germinates quickly but grows incredibly slowly. Its most rapid growth occurs when planted near a water source; its roots seek out water, sensing it and growing toward any source, even breaking through pipes or well walls to access it. However, the tree can live and thrive on less than 8 inches of rainfall per year in some of the hottest, driest climates on Earth. The hotter and more consistent the sunlight, the healthier the tree, and clay that grows little else nourishes it. The leaves resemble those of succulents, and are often consumed for their moisture by desert animals and people. When in dryer conditions the mustard tree may only grow to about six feet tall, but in wet environments will grow up to 25 feet, an imposing sight.
On three separate occasions Jesus explained the power of faith using the image of the mustard seed. He said that even faith as small as a mustard seed could do such impossible things as moving a mountain from one place to another or uprooting a mature tree to plant it in the sea. I have known the analogy all my life, but grasping such a thing is difficult when we tend to think of big and small as opposite limits of size.
God doesn’t think in limits. Just as a day and a thousand years are the same to Him, big and small hold no meaning in a physical sense. Instead, he sees potential. The tiny mustard seed has no strength of its own, no power to impress our human sensibilities, yet in the harshest, most unexpected conditions, life can be induced to spark within it. The germs of faith wake under similar circumstances. Like the mustard tree, faith does not become full overnight. It grows, millimeter by millimeter, over a lifetime. It can outlast some of the hardest circumstances life can throw at it, although often in hard times it merely exists, eking out drops in desperation but not finding enough to grow any larger. When the nourishing rain of an answered prayer, an encouraging word, a relief from a trial arrives, it grows again and fills new leaves with nourishment to hold in reserve for the next difficulty.
Also like the mustard tree, the roots of faith reach out endlessly with insatiable need. Faith knows its source, and will move in that direction only no matter what gets in the way. It cannot be stopped; even when we feel like we are barely hanging on, faith looks for any sign of God in the darkness and dirt of life and drinks it thirstily. If there were no water to be found, the tree would die – it cannot manufacture its own nutrition – but those roots can find and use any trace of moisture. Faith without nourishment would be nothing -a shriveled, rotten trunk – but unlike water God is always there to be found.
When Jesus’ disciples woke Him in the storm, He told them their faith was weak and small but He still stopped the storm. When they failed to cast out demons in His name He told them their faith was weak and small but He still cast out the demons. When a man begged for healing for his son and said he wanted to believe but needed help making faith stronger, Jesus healed the man’s son. When Moses hid in the wilderness for forty years because what he thought he was supposed to do for God failed, God became fire in a bush and told him he was chosen for a purpose because of his faith. How many more have been planted while tiny and insignificant, then nourished by God’s eager help into trees of faith to feed and harbor weak and searching souls?
“It’s like a mustard seed that a man took and sowed in his garden. It grew and became a tree, and the birds of the sky nested in its branches.” Luke 13:19 CSB
God will feed any faith we are capable of placing on Him, including the mere desire to have faith. Are you a mustard seed? How high will you grow?
