Let the peoples praise you, O God; let all the peoples praise you! (Psalm 67:3, 5)

Why does God demand we must praise God?

C.S. Lewis:

Just as men spontaneously praise whatever they value, so they spontaneously urge us to join them in praising it: “Isn’t she lovely? Wasn’t it glorious? Don’t you think that magnificent?”

The Psalmists in telling everyone to praise God are doing what all men do when they speak of what they care about. My whole, more general, difficulty about the praise of God depended on my absurdly denying to us, as regards the supremely Valuable, what we delight to do, what indeed we can’t help doing, about everything else we value.

I think we delight to praise what we enjoy because the praise not merely expresses but completes the enjoyment; it is its appointed consummation. It is not out of compliment that lovers keep on telling one another how beautiful they are; the delight is incomplete till it is expressed.

There is the answer — the solution to the apparent egomania of God in demanding us to praise him! It is a demand for our greatest happiness. We praise what we enjoy because the delight is incomplete until it is expressed in praise. If we were not allowed to speak of what we value and celebrate what we love and praise what we admire, our joy would not be full.

So, if God loves us enough to make our joy full, he must not only give us himself; he must also win from us the praise of our hearts — not because he needs to shore up some weakness in himself or compensate for some deficiency, but because he loves us and seeks the fullness of our joy that can be found only in knowing and praising him, the most magnificent of all beings.

If he is truly for us, he must be for himself! God is the one Being in all the universe for whom seeking his own praise is the ultimately loving act. For him, self-exaltation is the highest virtue. When he does all things “to the praise of his glory” (Ephesians 1:12, 14), he preserves for us and offers to us the only thing in all the world that can satisfy our longings.

God is for us! And the foundation of this love is that God has been, is now, and always will be for himself.
