The strongest faith is subject at times to shakings, as the stoutest ships are to tossings, as the wisest men are to doubtings, as the brightest stars are to twinklings. Therefore, Christian, if at certain times you should not be sensible of the growth of your faith, yet do not conclude that you have no faith. Faith may be in the habit, when it is not in the act; there may be life in the root of the tree, when there are neither leaves, blossoms, nor fruit upon the tree; but they will show themselves in the spring, and so will the habits of faith break forth into acts, when the Sun of righteousness shall shine forth, and make it a pleasant spring to the soul.
