God's love is fundamentally different from human love because it's permanent, unchanging, and flows from His very nature rather than being an emotion. Psalm 36 contrasts the darkness of wickedness with the magnificent reality of God's steadfast love, described as extending to the heavens and serving as our refuge. David shows us that God is the fountain of life itself, providing protection under His wings and inviting us to feast at His table. Christmas represents the ultimate expression of this divine love through God sending His Son to walk among us. We're called to accept this undeserved love and become channels of it to others, reflecting the same loyal, enduring love that God shows us.
