Jonathan Edwards reminds us of the foolishness of seeking true and lasting happiness outside of the One who is truly excellent:
"Worldly men imagine, that there is true excellency and true happiness in those things which they are pursuing. They think that if they could but obtain them, they should be happy; and when they obtain them, and cannot find happiness, they look for happiness in something else, and are still upon the pursuit.
But Christ Jesus has true excellency, and so great excellency, that when they come to see it they look no further, but the mind rests there. It sees a transcendent glory and an ineffable sweetness in him; it sees that till now it has been pursuing shadows, but that now it has found the substance; that before it had been seeking happiness in the stream, but that now it has found the ocean"
("Safety, Fullness, and Sweet Refreshment, to Be Found in Christ" Jonathan Edwards on Knowing Christ, 169-170).
