Ye are all the children of light, and the children of the day.–I THESS. v. 5.
_Light is sown for the righteous, and gladness for the upright in heart_.–PS. xcvii. 11.

Serene will be our days and bright, And happy will our nature be, When love is an unerring light, And joy its own security.
W. WORDSWORTH.
Nothing can produce so great a serenity of life, as a mind free from guilt, and kept untainted, not only from actions, but purposes that are wicked. By this means the soul will be not only unpolluted, but not disturbed; the fountain will run clear and unsullied, and the streams that flow from it will be just and honest deeds, ecstasies of satisfaction, a brisk energy of spirit, which makes a man an enthusiast in his joy, and a tenacious memory, sweeter than hope. For as shrubs which are cut down with the morning dew upon them do for a long time after retain their fragrancy, so the good actions of a wise man perfume his mind, and leave a rich scent behind them. So that joy is, as it were, watered with these essences, and owes its flourishing to them.
