A few weeks ago, I wrote a post on what the Marines taught me about Christianity. In that post, I contrasted the notions of joining something, like a church or a civic club or an email list, and becoming something, which carries with it an identity change.
JOIN - 1 a : to put or bring together so as to form a unit <join two blocks of wood with glue> b : to connect (as points) by a line c : ADJOIN
2 : to put or bring into close association or relationship <joined in marriage>
3 : to engage in (battle)
4 a : to come into the company of <joined us for lunch> b : to associate oneself with <joined the church>
Joining is a process of connecting to, or associating with something or someone. On the other hand, becoming is a process of developing into something completely new or different - "to come into existence; to come to be."
And so, once again I say it: I don't want to join Christianity. I want to become a Christian.
