Proverbs 27:20 (KJV) states, “Hell and destruction are never full; so the eyes of man are never satisfied.” This verse uses the insatiable nature of the grave as a metaphor to illustrate that human desires are similarly endless and cannot be fully satisfied. Our appetites for more, whether it be material possessions, power, or other desires, are limitless, often leading to constant longing and frustration.
The psalmist, being a man of understanding, sings, “Turn my eyes away from worthless things; revive me with Your word” (Psalm 119:37, BSB). Job, also a man of wisdom, made this covenant with his eyes: “I have made a covenant with my eyes. How then could I gaze with desire at a virgin?” (Job 31:1, BSB).
Sin originates not from external sources but from within us (Matthew 15:19). If sin were external, it would have no power over us. However, since sin dwells within us, it is inherently fatal. While temptation may come from outside, our sinful nature is internal. As descendants of Adam, we have all inherited this old, corrupted, and defiled disposition. When external temptation arises, it is met with our internal sinful responses, leading to the act of sin.
However, when our hearts yield to the influence of the Spirit of God, our consciences are awakened. The sinner begins to discern the depth and sacredness of God’s holy law, which is the foundation of His government in heaven and on earth. We receive guidance on how to use our eyes: “My son, attend to my words; incline your ear unto my sayings. Let them not depart from your eyes; keep them in the midst of your heart” (Proverbs 4:20-21, KJV). Let your eyes look straight ahead and let your eyelids look directly before you (Proverbs 4:25, KJV).
