We have very little control of anything in life. This brings great fear. So we try to control the fear by letting go of control. But this is simply another vain attempt to control. Just as we cannot control life, we cannot control control.
The only way out is to recognize that control is an illusion. We have no control. Life is a ride, and God is the builder of this ride, and Jesus is riding it with us, so we can just enjoy all the ups and downs of life.
