Proverbs 4:18

But the path of the just is as the shining light, like the growing brightness of dawn as it heralds and ushers in the day, that shineth more and more unto the perfect day, growing brighter with each succeeding minute, the comparison of the moral conduct of the righteous with the light of the rising sun being most appropriate; for he goes forward to ever greater clearness and perfection, not only in his inward knowledge, but also in its outward manifestation.
