Have you ever considered the fact God made you to need to rest? We enjoy staying active and find delight in working hard accomplishing what God gives us to do. But this cannot come at the expense of true rest. God made the human body that it would break if it does not have significant rest every day!
This rest is illustrative of the spiritual rest that we also need. You will function in prime condition only when you are finding spiritual rest in God. God is the all sufficient anchor for our soul that brings calm to life even when the circumstances cry otherwise. These times of rest are not found at a vacation or resort, but in the joy of the Lord.
