This is about a guy who takes a funny-looking stick and hits a tiny little ball and people pay him lots and lots of money for doing this.

Every one of us has need of God as a tree needs to be rooted in a place with an unfailing supply of water.  We must not behave with presumption, as if we could casually postpone a bond with God until the time that suits us.

Our call from God makes itself felt when we are caught up in wonder and awe.  Our sense of awe may well be connected with a sense of unworthiness, as in the case of Isaiah, Paul, and Peter.  We are aware of our absolute need for God, and thus God can take command of our life.
