I therefore, a prisoner for the Lord, urge you to walk in a manner worthy of the calling to which you have been called, 2with all humility and gentleness, with patience, bearing with one another in love, 3eager to maintain the unity of the Spirit in the bond of peace. 4There is one body and one Spirit—just as you were called to the one hope that belongs to your call— 5one Lord, one faith, one baptism, 6one God and Father of all, who is over all and through all and in all. – Ephesians 4:1-6 (ESV)

1. Unity drives our actions

And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses, by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross. – Colossians 2:13-14 (ESV)

A. Walk worthy of our calling

B. Paul appeals as a prisoner for the Lord

2. Unity prompts our attitudes

A. All Humility and gentleness

Precisely because he has been granted to know God, the Christian man is a man of lowliness. He regards his knowledge as small and lowly because he has seen the omniscient God. He regards his strength as small and lowly because he has seen the omnipotent God. He regards his righteousness as small and lowly because he has seen the Holy One of Israel. And since the Christian is oriented on God and not man, he is not puffed up by any little superiority he may have over other men. – John Piper

Do nothing from rivalry or conceit, but in humility count others more significant than yourselves. Let each of you look not only to his own interests, but also to the interests of others. Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but made himself nothing, taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross. – Philippians 2:3-8 (ESV)

B. Longsuffering and bearing with each other in love

3. Unity fixes our aim

A. Make every effort

B. Maintain the unity of the Spirit

A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. By this all people will know that you are my disciples, if you have love for one another.” - John 13:34-35

C. Through the bond of peace

4. Unity firms our agreement

A. One body, one Spirit, one hope

For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ. For in one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and all were made to drink of one Spirit. – 1 Corinthians 12:12-13 (ESV)

B. One Lord, one faith, one baptism

“You know that the rulers of the Gentiles lord it over them, and their great ones exercise authority over them. It shall not be so among you. But whoever would be great among you must be your servant, and whoever would be first among you must be your slave, even as the Son of Man came not to be served but to serve, and to give his life as a ransom for many.” – Matthew 20:25-28 (ESV)

C. One God and Father of all
