The Lord’s instruction is right; it makes our hearts glad. His commands shine brightly, and they give us light.
Psalm 19:8 CEV
The heavens declare the glory of God for all to see (as written in the first part of this Psalm) but it is not until we take His Word personally and allow it to dominate our thoughts and actions that we are filled with the light of His love and given indescribable joy.
Other translations describe God's Word as perfect, sure, pure, clean and true. We are looking for truth and purity in this world that is rotten with sin and here it is before our very eyes. Following God's commands gives me peace.
