"What actually drives us to unrest is rooted in our hearts, usually idolatry. For example, the workaholic sacrifices rest to the god of success, power, and productivity. This pattern can be seen in almost all areas of our life. The good news is, God is not silent about our need for rest nor has He left us without good reason or motivation for rest. The Bible is very clear that humans need rest, and interestingly enough, rest teaches us something about God."
