The guys at Of First Importance have created a site to help us remember just that – the gospel is the center.  Each day a new quote about the gospel is posted.  They’ve created a widget and an email feed to let the quotes pop up each day.

Here’s today’s post:

“The office of the law is to show us the disease, in such a way as
to show us, at the same time, no hope of cure: the office of the gospel
is, to bring a remedy to those that were past hope. For as the law
leaves a man to himself, it condemns him, of necessity, to death; while
the gospel, bringing him to Christ, opens the gate of life.”

- John Calvin, Calvin’s Commentaries, vol. XX, p. 178.
