Paul writes that we are all heirs, all members of one body, all sharers in the promise of Christ (Ephesians 2:6). Paul knew what it was like to attack other people because of their beliefs. He also knew what it was like to be attacked because of his beliefs. In fact he was in prison for his beliefs when he wrote his letter to the church in Ephesus. One might say that unity was a burning issue for him, a matter of great consequence. So he urged unity in his churches. He knew that it is the common witness of the church that will speak to the "rulers and authorities in the heavenly realms." And that common witness cannot be achieved if we in the church don't recognize that we are all members of one body, part of one another, one flesh, with Christ as the head. We cannot put up walls against one another or attack each other without damaging the common witness we are supposed to support.
Let us receive Paul's prayer on our behalf today. "For this reason I kneel before the Father, from whom his whole family in heaven and on earth derives its name. I pray that out of his glorious riches he may strengthen you with power through his Spirit in your inner being, so that Christ may dwell in your hearts through faith. And I pray that you, being rooted and established in love, may have power, together with all the saints, to grasp how wide and long and high and deep is the love of Christ, and to know this love that surpasses knowledge -- that you may be filled to the measure of all the fullness of God.
"Now to him who is able to do immeasurably more than all we ask or imagine, according to his power that is at work with us, to him be glory in the church and in Christ Jesus throughout all generations, for ever and ever! Amen." (Ephesians 3:14-21)
