I have friends who hide in their bedroom for three days every time they have another birthday. That's what brings the wrinkles! I didn't care when I turned 30 or 40 or 50.
There was no identity crisis in the life of Jesus Christ. He knew who He was. He knew where He had come from, and why he was here. And he knew where He was going. And when you are that liberated, then you can serve.
