Let me share with all of you something I've learned about the need for rest and how it can appropriately be applied to our lives. In weightlifting, for example, there is great resistance that causes my muscles to bulk up. But for that resistance to have it's greatest impact, I must also rest right afterward. First, there is great resistance, then there is great rest. As I repeat that scenario throughout the week - resistance and rest - my muscles become stronger.
Now some of you are giving your life resistance without rest. If you do that, you are heading for diasaster. Yes, resistance in life in necessary. It is a part of living, but whenever you have resistance, give yourself some rest. Take your vacation time. Take some time to get away. If you're burning the candle at both ends, you're not as bright as you think you are. Get some rest as well as resistance. That's how you grow.
