Plunge a sponge into Lake Erie. Did you absorb every drop? Take a deep breath. Did you suck the oxygen out of the atmosphere? Pluck a pine needle from a tree in Yosemite. Did you deplete the forest of foliage? Watch an ocean wave crash against the beach. Will there never be another one? Of course there will. No sooner will one wave crash into the sand than another appears. Then another, then another. This is a picture of God's sufficient grace. Grace is simply another word for God's tumbling, rumbling reservoir of strength and protection. It comes at us not occasionally or miserly but constantly and aggressively, wave upon wave. We've barely regained our balance from one breaker, and then, bam, here comes another.
