Psalm 119 is Scripture’s longest psalm and a passionate love song to God’s Word. It celebrates the beauty, authority, and reliability of God’s law, statutes, and promises, using an acrostic structure built on the Hebrew alphabet to express fullness and completeness of devotion. The psalmist wrestles honestly with affliction, persecution, and inner weakness, yet keeps returning to the conviction that God’s word gives life, wisdom, purity, and guidance. Famous lines such as “Your word is a lamp to my feet and a light to my path” capture its central theme: the believer’s daily walk is sustained, corrected, and encouraged through continual meditation on and obedience to what God has spoken. Psalm 119 ultimately calls us to delight in God’s instructions, cling to them in suffering, and trust that His commands are good, true, and life-giving for all who seek Him wholeheartedly.
