Susan and I once built a house on a fishing lake in central Georgia. We chose the house site carefully, saving as many trees as possible.
Beside the house was a majestic oak tree we particularly loved. One day as we arrived at our lakehouse, we discovered the tree had fallen during a winter storm. We were heart-sick.
But as I examined the tree more carefully, I discovered while it looked healthy on the outside, it was rotten on the inside. The storm had felled a dead tree.
A lot of people are like that tree. They look good to the outside world, but on the inside they are unhealthy, sick, and even dead. It is your core, your inner integrity which matters most in life. It is the only thing that will sustain you during the storms of life.
