1 Corinthians 10:31
Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God.
This becomes clearer as we move through Isaiah:
I give water in the wilderness, rivers in the desert to give drink to my chosen people, the people whom I formed for myself that they might declare my praise. (Isaiah 43:20–21)
Sing, O heavens for the Lord has done it; shout, O depths of the earth; break forth into singing, O mountains, O forest and every tree in it! For the Lord has redeemed Jacob and will be glorified in Israel (Isaiah 44:23).
But Isaiah 48:9–11 makes even clearer what it means for God to seek his own glory in creating and redeeming his people:
For My name’s sake I defer my anger,
for the sake of My praise I restrain it for you,
that I may not cut you off.
Behold, I have refined you but not like silver;
I have tried you in the furnace of affliction.
For My own sake, for My own sake I do it,
for how should My name be profaned?
My glory I will not give to another.
