The LORD is gracious and merciful, slow to anger and abounding in steadfast love. -Psalm 145:8
My own love vacillates like the tide–it is dependent upon my mood and circumstance. In contrast, His love is solid, steadfast.
The LORD is good to all: and his tender mercies are over all his works. Psalm 145:9
Tender mercies–this phrase more literally means “cherish, as the womb does a fetus.” It is easier to see the injustices of the world and of our own little worlds, much harder (at least for me), to step out in confidence and say “The Lord is good to all.“
His goodness must be quite a different thing than our own, just as His love is steadfast while our own vacillates with the events of life and our moods. Oh, to be good to all and steadfast in love! Oh to be able to see and trust those qualities in Him, to frame our world with that reality.
Perhaps that is what David is after when he starts this psalm wtih “I will extol Thee O God.”
To extol is to raise up, lift up, promote, heave up, to be highly active. “I will extol thee, my God, O King.” We are to make ourselves highly active in extolling our God and His true character–the characteristics reflected in His world, not in our inconstant and fallible mind and heart:
“They shall abundantly utter the memory of thy great goodness, and shall sing of thy righteousness. ” -Psalm 145:7
Matthew Henry makes a great point here:
“He would give glory to God, not only in his solemn devotions, but in his common conversation. If the heart be full of God, out of the abundance of that the mouth will speak with reverence, to his praise, upon all occasions. What subject of discourse can we find more noble, more copious, more pleasant, useful, and unexceptionable, than the glory of God?”
