Walk in a manner worthy of your calling.

I find it interesting how Paul always begins his letters building a foundation of theology and then gets to the application in the second half of the letter. It's always more fun delving into the theology and discussing the meaning than reading about what we should do with it. But knowledge without function and purpose is just hot air.
In Ephesians 4 Paul gets to the point by reminding us to walk worthy of our calling. And gives the characteristics of one who is a child of God. Isn't it interesting that these are not characteristics that are preached about on Sunday very often; humility, gentleness, patience and relating with each other in love. He gets more specific in the middle of the chapter but ends again with the admonition to be "kind and merciful, and forgive others, just as God forgave you because of Christ." And I must always remember as Paul taught in the previous chapters that I can't do this on my own, but only through the power God provides through the Spirit.
