“I will open my mouth in parables, I will announce what has lain hidden from the foundation of the world.” Jesus (Matthew 13:31-35)
If you have not noticed, God prefers the small and insignificant. Instead of Rome, He chooses Bethlehem. Instead of the learned Pharisees, He chooses a group of unschooled anglers. The Apostle Paul defines mustard seed Christianity this way: “God chose what is low and despised in the world, even things that are not, to bring to nothing things that are,”
Faith the size of a mustard seed refers to the smallness of the Christian. After a lifetime “taking up your cross,” the Christian become the size of a mustard seed. After practicing, “I must decrease so that He might increase,” he/she consistently prays with no thought of him/herself only thinking of God’s will. God is the God of the poor, the simple, and those whose hope is in God alone.
You do not “MUSTER” up this kind of faith. You become this kind of faith. People find mustard seed faith when they submit to the sovereignty of God. When Habakkuk witnessed Judah’s sin and future ruler, God is advised: “The just shall live by faith.”
Mustard Seed Faith is creative like Genesis. You are moving in concert with God. The reason we fear is that we are out of sync with the plan of God. Habakkuk refers to this as sin. Because of our crazy view of faith and forgiveness, we dismiss sin and mustard seed faith evaporates. God hates greed even if it is a part of our capitalistic culture (Hab. 2:6-8). God is opposed to our ruthless/heartless abortions (vv. 9-11). God is always opposed to being drunk or high (cf. 15-17). When enough people in society begin to live like mustard seed Christians, then the Church will be big enough to support society (cf. “birds perching on its branches.”)
