Joni, long ago, got me hooked on the Jesus Calling book. I read an excerpt the other day that especially ministered to me. I've been feeling quite old lately. So far removed from my volleyball and basketball days. And then I read this:
"I am your living God, far more abundantly alive than the most vivacious person you know. The human body is wonderfully crafted, but gravity and the inevitable effects of aging weigh it down. Even the most superb athlete cannot mantain his fitness over many decades. Lasting abundant life can be found in Me alone. Do not be anxious about the weakness of your body. Instead, view it as the prelud to My energy's infusion into your being.
As you identify more and more fully with Me, My Life becomes increasingly intertwined with yours. Though the process of aging continues, inwardly you grow stronger with the passing years. Those who live close to Me develop an inner aliveness that makes them seem youthful in spite of their years. Let My Life shine through you, as you walk in the light with Me."
