I believe that Scripture lays out several principles on how to keep our lives pure before the Lord. These principles are found in Psalm 119:9-16. 1. Obey the Word. (vss 9-10). 2. Treasure the Word in your heart. (vss 11-14). 3. Meditate upon the Word. (vs 15). 4. Do not forget the Word. (vs 16). In other words, the Word of God is to have a primary place in our daily lives.
