A Christian is one who, in response to Christ’s call to “come, follow me,” seeks to know, love and serve Christ. For many, to be a convert is to respond to this call and to choose to orient one’s life in response to it. And this is good—very good. Yet our only hope for transformation is that we be drawn into the life of Christ such that we live our lives in him, in union with Christ individually and together with others who are growing up into him who is our head.
