Life in itself is unable to supply the key to the questions of identity, meaning, purpose, value and destiny. Only God holds the key, and he must be trusted with it. He does not make copies of the key for us to use. You do not get to keep God's key in your back pocket. Sooner or later, if you are a believer, you are going to have to actually trust God to keep the key of life.
Love that bit about no copies. Beautiful.
