God wants us to understand what it really means to have faith the size of a mustard seed. Faith is a highly complex word and idea. God tells us to have faith, walk in faith, build our faith, and proclaim our faith. Faith is, therefore, something that we can possess, live out, grow, and ultimately share with others. Jesus spoke in parables to the people, and he often used seeds, more specifically the mustard seed. This blog post contains a corresponding prayer via @KrystalRSimpson
