There is one body and one Spirit, just as also you were called in one hope of your calling; one Lord, one faith, one baptism, one God and Father of all who is over all and through all and in all. Ephesians 4:4-6
The word one is used here 7 times in 3 verses. If you read the first three verses of Ephesians chapter 4, Paul is challenging the people of the church to walk in unity and love. As humans, we seem to love divisions. We create new groups, sections or committees for everything that comes our way. The question I ask myself is: "why?" Why do we divide ourselves, as believers, when throughout Scripture we are called to forget the dividing lines and walk in unity?
What would happen to the church if we decided to unite together as denominations and begin spreading the love of Christ as one? What would happen if we focused on the fact that we worship One Lord, One God, One Father instead of worrying about all of the little distinctions between Baptist, Presbyterian, Methodist and the others? What would happen if we told people we were simply followers of Jesus Christ, His disciples, instead of saying I am Southern Baptist or I am Lutheran?
We are called to walk in Unity. We are called to walk as One Body. We are called to preserve the Unity of the Spirit (vs. 3).
