Consider for a moment: If you got into a conversation with someone, a person you just met, and they said: "Tell me about yourself." What would you say? What defines you as a person? How would you identify yourself to others? What labels would you use? What matters to you the most?
There are many things in this life that compete for our interest and for our time. Many of them are good things. But for a Christian, for one who is committed to following Jesus as Lord, there is one thing that rises above all others, one thing that is primary.
What should define us above all else and set the contours of our lives is belonging to God and to His people. As Christians we are born again and placed into a family—members together of the body of Christ. Our lives together are bound up in Christ and His church.
