“Identity is a complex set of layers, for we are many things. Our occupation, ethnic identity, etc., are part of who we are. But we assign different values to these components and thus Christian maturing is a process in which the most fundamental layer of our identity becomes our self-understanding as a new creature in Christ along with all our privileges in him.
- Timothy Keller “Gospel Christianity” Course 3 (Redeemer Presbyterian Church, 2003), 141.
