John Calvin:

“If we wish to have the sun, for no other cause than to stand idly gazing upon it like people in wonder, how futile that would be. The doctrine of the gospel, it shines, not for us to spend our lives debating silly speculations but in order that we should get to work, and each one of us discover where we can and ought to do service, and as a result make the most of the light God’s given us.”
