Psalm 52:1 Why do you boast in evil, O mighty man? The lovingkindness of God endures all day long.
Psalm 66:20 Blessed be God, who has not turned away my prayer, nor His lovingkindness from me.
Psalm 6:4 Return, O Lord, rescue my soul; save me because of Thy lovingkindness.
Psalm 52:1 really hit me one day. I read it and thought of all those 'tough guys' or men who do evil, hurt other people, oppress women and how they thought the were so tough. And you know, I realized that this verse is stating point blank that God is not impressed with their strength. They boast in their might and ability to get away with evil. But God, who's might far surpasses the might man's puts His stock and heart in lovingkindness, a lovingkindness that endures (has the strength to last) all day. It is far better than what any mighty man can boast in.
Love Psalm 66:20 because it assures us that God doesn't turn away our prayers from Him nor turn away His lovingkindness toward us.
And the last one, the psalmist calls on God to save him, not because the psalmist deserves it... but because of God's lovingkindness, which I'm slowly learning is one of the (if not THE) most powerful forces well ever know.
Dear God, help us to see the power and endurance of Your lovingkindness.
