Baseball calls it a curve ball for a reason: you just don't know where some pitches will land. Your ace could get injured. Your golden glover could err. Your team could sit through a rain delay. Your manager could get ejected. Your bench must be broad and deep enough to overcome.

People have this idea that the more pious and devout I am, the more successful I am. Which is very dangerous. If you look at faith in that way, you're bound to fail at both - spiritually and in your career.
