O LORD, in your strength the king rejoices,
and in your salvation how greatly he exults!
Be exalted, O LORD, in your strength!
We will sing and praise your power. —Psalm 21:1 and 13 ESV
C. H Spurgeon comments on these verses in The Treasury of David:
Let us with our Lord rejoice in salvation, as coming from God, as coming to us, as extending itself to others, and as soon to encompass all lands. We need not be afraid of too much rejoicing in this respect; this solid foundation will well sustain the loftiest edifice of joy. The shoutings of the early methodists in the excitement of the joy were far more pardonable than our own lukewarmness. Our joy should have some sort of inexpressibleness in it…
The exaltation of the name of God should be the business of every Christian; but since such poor things as we fail to honour him as he deserves, we may invoke his own power to aid us. Be high, O God, but do thou maintain thy loftiness by thine own almightiness, for no other power can worthily do it.
