Use temporal things but desire eternal things. You cannot be satisfied with any temporal goods because you were not created to enjoy them.
Even if you possessed all created things you could not be happy and blessed; for in God, who created all these things, your whole blessedness and happiness consists.
–Thomas à Kempis
Updating the wording a bit, I think I’d say it this way:
Use material possessions, but desire the things of God. Because you cannot find true satisfaction in material possessions, because you were not designed to find contentment in these things.
God did create us to enjoy the excellent things he created for us, but they cannot bring full satisfaction. Only the Creator can do so. And we know that many people who achieve exorbitant wealth are able to possess all the things they ever wanted and yet still find themselves miserable and looking for satisfaction in something else… some of them even committing suicide when they realize that the things they most wanted in life left them empty.
Each of us has a God-shaped hole in our hearts and only He is able to fill it up perfectly to bring us full contentment. Make sure that you are not trying to be satisfied with the things of this world, instead seek to be satisfied by the Creator of this world – who also created you and knows how to meet your deepest longings!
