I will sing of the steadfast love of the Lord, forever;
with my mouth I will make known your faithfulness to all generations.
For I said, “Steadfast love will be built up forever;
in the heavens you will establish your faithfulness.”
You have said, “I have made a covenant with my chosen one;
I have sworn to David my servant:
‘I will establish your offspring forever,
and build your throne for all generations.’” Selah
Let the heavens praise your wonders, O Lord,
your faithfulness in the assembly of the holy ones!
For who in the skies can be compared to the Lord?
Who among the heavenly beings is like the Lord,
a God greatly to be feared in the council of the holy ones,
and awesome above all who are around him?
O Lord God of hosts,
who is mighty as you are, O Lord,
with your faithfulness all around you?
C. H Spurgeon opens his commentary on Psalm 89, in The Treasury of David, like this:
Whatever we may observe abroad or experience in our own persons, we ought still to praise God for his mercies, since they most certainly remain the same, whether we can perceive them or not. Sense sings but now and then, but faith is an eternal songster. Whether others sing or not, believers must never give over; in them should be constancy of praise, since God’s love to them cannot by any possibility have changed, however providence may seem to frown. We are not only to believe the Lord’s goodness, but to rejoice in it evermore; it is the source of all our joy, and as it cannot be dried up, so the stream ought never to fail to flow, or cease to flash in sparkling crystal of song. We have not one, but many mercies to rejoice in, and should therefore multiply the expressions of our thankfulness.
