Cure for the Common Life by Max Lucado is an insightful look into stopping an apathetic attitude toward your relationship with God.
Here are some quotes from the book:
“The cure for the common life begins and ends with God.”
“Worship God. Applaud him loud and often. For your sake, you need it. And for heaven’s sake, he deserves it.”
“In contemporary society our Adversary majors in three things: noise, hurry, and crowds. If he can keep us engaged in ‘muchness’ and ‘manyness,’ he will rest satisfied.” -Richard Foster
It is a great book about slowing down and focusing on your relationship with God. I would recommend it. Enjoy!
