From the Preface:
Not only is Psalm 119 the longest Psalm, but its particular focus is on the way the Word of God is to operate in the life of those who seek, serve, and submit to God. This is what makes it an important Psalm to consider and meditate on.
My hope and prayer are that as we consider what the Psalmist wrote, we will see through the Psalm like a lens. And as we peer through the images and illustrations offered to us, we will understand more deeply what God is calling us to.
