Proverbs 4:18-19

But the path of the [uncompromisingly] just and righteous is like the light of dawn, that shines more and more (brighter and clearer) until [it reaches its full strength and glory in] the perfect day [to be prepared]. [II Sam. 23:4; Matt. 5:14; Phil. 2:15.] The way of the wicked is like deep darkness; they do not know over what they stumble. [John 12:35.]
