“Your only safety lies in placing yourself in circumstances which will make exertion necessary, and which will secure Divine assistance. Never mind your infirmities. You have nothing to do with them. Your business is to trust, and to go forward. If you wait till the sea becomes land, you will never walk on it. You must leave the ship, and, like Peter, set your feet upon the waves, and you will find them marble.”

Indeed, a man's sluggish current may not be called love, compared with the rushing fountain that wells up when a boy's heart is struck with the heavenly rod. If you would taste love, drink of the pure stream that youth pours out at your feet. Do not wait till it has become a muddy river before you stoop to catch its waves.
