The world won't stop without you. You can trust God to fill in the gaps left by your presence.
Does your ministry (personal or professional) demand a lot of your time? What happens when you get sick, or need an unplanned break?
God doesn't need you to keep the universe ticking over. While our lives never stop, and our growth in Christ continues every moment, sometimes our rest is a part of the bigger action.
Learning to rest, learning to show the world that you do trust God with what you can't do. Knowing that anyone else could do your work, if God wills it.
Enjoy your holiday breaks to the glory of God.
