God created us all with the need to rest. He never meant for us to work so much that we never took time for ourselves. Resting is important for the body to go forward. In scripture we see where God sanctioned the seventh day as a day of rest. Now I know there is an important theological lesson behind it. However, we must also see the practical lesson as well.
When one takes time to rest, it allows his or her body to get charged back up for what might lie ahead. If one continues using a rechargeable battery but never recharge it, it will finally die. The same is with us. We need rest, we need time to recharge.
I encourage you that if you have not taken time to rest, do so soon. You will find it that by practicing it, you will be able to deal with what lies ahead.
Be encouraged today.
