On December 9, 1987, a squirrel chewed through a power line in Connecticut, and the NASDAQ’s vast financial machinery blinked, sighed, and went dark. Some of the world's largest corporations stood limp and listless. Global economies watched, sweating bullets for nearly an hour and a half. All because of one tenacious, furry rodent.

Scripture tells many stories of something or someone small making a big impact. But God can turn meagerness into something mighty. John recounts how Jesus fed a hungry crowd (five thousand men, probably fifteen thousand with women and children included) when “a boy with five small barley loaves and two small fish” handed over his small lunch (John 6:9). In the Old Testament we remember that a young shepherd boy named David trusted God and slayed a giant (1 Samuel 17). And Christ repeatedly insisted that the kingdom of God is something like a mustard seed, “the smallest of all seeds” (Matthew 13:32 ).

When we ponder the many complex global crises in addition to the bewildering concerns in our own neighborhoods and families, we’re tempted to believe that our seemingly small efforts lack power. But Scripture tells us to act in obedience and trust as God helps us—assured that with Him, small things can become mighty (John 6:10-12).
