Knowledge and personality make doubt possible, but knowledge is also the cure of doubt; and when we get a full and adequate sense of personality we are lifted into a region where doubt is almost impossible, for no man can know himself as he is, and all fullness of his nature, without also knowing God.

Providence has nothing good or high in store for one who does not resolutely aim at something high or good. A purpose is the eternal condition of success.
