It’s a mystery why things happen the way they do sometimes. It’s a mystery why God doesn’t always act in the way we expect. And that mystery is a weighty matter that God invites us to carry as we struggle to believe.

If people commit themselves to the church, they will undoubtedly suffer.  The church will fail them and frustrate them, because it is a human 
institution.  Yet it will also bless them, even as it fails. A living, breathing congregation is the only place to live in a healthy  relationship to God. That is because it is the only place on earth where Jesus has 
chosen to dwell."

Serving matters in the church, whether it's banging on the drums, changing a diaper, or leading a small group. When we volunteer and serve, we make it possible to leave the light on. We make it possible for people who are seeking God to find Him.
