Chi Alpha...
What's with the name?
As a follower of Jesus, we take seriously the call in 2 Corinthians 5:20 to be "Christ's Ambassadors" to the world. Each of us who takes on the identity of “Christian” becomes Christ’s ambassador – or christou apostoloi in Greek, which we shorten to the first letters “Chi” and “Alpha” or XA. Through the power of the Holy Spirit, we carry the presence of God everywhere we go! What an honor to be used by God to further His Kingdom!
"We are therefore Christ’s ambassadors, as though God were making his appeal through us. We implore you on Christ’s behalf: Be reconciled to God." 2 Corinthians 5:20 (ESV)
