What does it mean to have a heart that longs for God's Word?

The psalmist's expression of longing for God's commandments reveals a believer's innate desire for spiritual growth and nourishment. This thirst for God's Word reflects an understanding that only through God's mercy can we be sustained. As indicated in Psalm 119:131, this longing equates to an awareness of our need for divine sustenance. Just as a hungry child eagerly opens its mouth for food, believers should eagerly seek the truths found in scripture, recognizing that God's mercy is the meal and drink that sustains their spiritual life.
