If all were perfect, what should we have to suffer from others for God's sake? But God has so ordained, that we may learn to bear with one another's burdens, for there is no man without fault, no man without burden, no man sufficient to himself nor wise enough. Hence, we must support one another, console one another, mutually help, counsel, and advise, for the measure of every man's virtue is best revealed in time of adversity -- adversity that does not weaken a man but rather shows what he is.
