"Living in Unity" Ephesians 4:4-6

Here Paul is speaking to the local church and reminding they are an interdependent body.  How can we be unified when we come from different backgrounds and have different preferences?  Our unity is found in our common faith, Spirit and Lord who reigns over all.  The idea of the Lone-Ranger Christian is no where to be found in the Scripture we are to walk as a unified body.  We are called to unity as a testimony of the Gospel because we have one Lord who unites us as one.  We each are a different part of the body but we are truly one.
