10 Bible Verses about Cooperation

The person who is not on my side is [actually] against me. And the person who does not gather [people to me] is [actually] driving them away [from me].

Have the same [good] thoughts toward one another. Do not [always] be thinking you are a "bigshot," but lower yourself to accept humble tasks [or, humble people]. Do not think you are so smart.

May God [who is the source] of steadfastness and encouragement, give you [a sense of] like-mindedness among yourselves, in harmony with [the example of] Christ Jesus, so that in [genuine] unity and with one voice, you people may honor the God and Father of our Lord Jesus Christ.

Now I urge you, brothers, through the name [i.e., by the authority] of our Lord Jesus Christ, that you should all agree in what you say, so that no divisions [continue] among you. Be restored [to unity] by having common thoughts and convictions [i.e., in spiritual matters].

For the human body is not made up of [only] one part, but of many parts. If the foot should say, "I am not part of the body because I'm not the hand," that does not mean it is not part of the body [does it ?]. And if the ear should say, "I am not part of the body because I am not the eye," that does not mean it is not part of the body [does it ?]read more.
If the whole body were an eye, how could it hear? If the whole body were an ear, how could it smell? But the way it is, God has placed each individual part in the human body just as it pleased Him. And if all the parts were one part, how could there be a [whole] body? But the way it is, there are many parts, but one body.

Do not team up with unbelievers [i.e., in close relationships, such as marriage, etc.]. For what do righteousness and wickedness have in common? Or, what fellowship can light have with darkness?

Finally, brothers, good-bye [or, "be glad"]. Be fully restored [spiritually]. Be comforted [or, "exhort one another"]. Think alike on things. Be at peace among yourselves. And the God of love and peace will be with you.

[Then] make me completely happy by being like-minded, having the same love [for one another], being united in spirit and having the same purpose.

I urge Euodia and I urge Syntyche to be like-minded in [fellowship with] the Lord.

Now to summarize: All of you should think alike. Be sympathetically understanding [toward one another]. Be loving toward [your] brothers [and sisters]. Be tender-hearted and humble-minded. Do not repay a wrong action with [another] wrong action, nor abusive [language] with [additional] abuse, but rather be a blessing [to one another]. For the purpose of your being called [by God] was so that you could receive a blessing [from Him eventually].
