Samuel Howard Miller
It is the rare person who, looking back over his life and seeing what he has done to it, hasn't sighed for a chance to redeem what he has cheaply used or carelessly ruined. If only somehow, somewhere, there was a way to live again the days we have darkened with our blind haste - the innumerable occasions when our indifference trod on all the pearls of God’s graciousness; the times when our pride, or our fear, or our meanness poured the acid of contempt over the fair countenance of another’s soul! If this grace were ours, how we would leap to the chance!
