“For the Lord God is a sun and shield; the Lord bestows favor and honor; no good thing does he withhold from those whose walk is blameless. Lord Almighty, blessed is the one who trusts in you.” (Psalm 84:11-12, NIV)
Imagine life before the advent of electricity: The activities of everyday living revolved around the hours of daylight. Nighttime activities were severely limited because lamp oil and candles were cumbersome, and expensive alternatives.
Perhaps we grasp the value of a shield a bit easier, if only because our cars have “windshields” that not only shield us from being buffeted by the wind as we zip along the streets and highways; but from bugs, rocks, and rainwater. A windshield is a “go/no-go item” for most motorists: If it is in place, you go; if not, you choose to ride with a friend.
The psalmist reminds us that the Lord God is both a sun and shield. Abide in God at all costs, and you will never dwell in darkness. Trust in Him at all times, and He will be your shield from perils both seen and unseen. – Luther
