A recent television documentary pointed out that the cheetah survives on the African plains by running down its prey. The big cat can sprint seventy miles per hour. But the cheetah cannot sustain that pace for long. Within its long, sleek body is a disproportionately small heart, which causes the cheetah to tire quickly. Unless the cheetah catches its prey in the first flurry, it must abandon the chase. Sometimes Christians seem to have the cheetah's approach to ministry. We speed into projects with great energy. But lacking the heart for sustained effort, we fizzle before we finish. We vow to start faster and run harder, when what we need may be not more speed but more staying power&md;stamina that comes only from a bigger heart. Motion and busyness, no matter how great, yield nothing unless we allow God to give us the heart.
