The great questions of life — Who am I? Where did I come from? Is there meaning and purpose? Where is God in suffering? — all intersect and are resolved only in communion. Preaching, when it understands itself, is invitation and preparation for communion. Fruitful service, rather than the justification for communion, only arises from it. Whatever does not arise from faith, no matter how impressive to the world, is sin. Real friendship happens only in communion. Every ending points back to communion. Every communicant participates in the new future that God stands ever ready to give to those who look to him in trust. The Christian life is retailing every day what we lay up for ourselves in communion.
