If nothing changed, if no one died and no one was born, life would become dull like the brown grass of late Summer or the brown, dead leaves of Fall. God gave us a changing world and a changing life to keep us challenged and lively and to keep us excited about life. There is something about the fear of change in our lives that brings an inward thrill. I don't have to be the same tomorrow that I am today. God calls us to change.
Growth is change.
Sometimes it hurts and sometimes it is pleasant. But it is always beneficial. Don't fear letting God make changes in your life. You are a creature designed for change. Do not resist.
