Pastor Kim explores Psalm 119:9-16, the Beth stanza, teaching how God's Word purifies sincere, submissive, and steadfast hearts. He addresses the challenges of a slippery world and internal depravity, showing that true cleansing comes from wholehearted seeking of God, hiding Scripture in the heart to avoid sin, worshipful learning, bold proclamation, joyful meditation, and delighting in God's statutes.
