4:18 path of the just. In contrast to “the path of the wicked,” whose way “is as darkness” (Proverbs 4:14,19), the believer’s path is illuminated by the “shining light” of God’s Word (Psalm 119:105; Proverbs 6:23), and “the light of the world,” Jesus Christ (John 8:12).

4:18 the shining light. The “light” that shines on the path to guide the “just” is, of course, the Lord Himself (Psalm 27:1,11; II Corinthians 4:6), through His inspired written Word (II Peter 1:19). This light eventually leads us to the land of “perfect day” where there is no more night (Revelation 22:5).
