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.

So, the large number of believers were united in heart and soul [i.e., mind and spirit] and not one of them said that anything he owned [really] belonged to him, but they shared all things in common.

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].

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.

So, [whatever happens], live your daily lives in such a way as to be worthy of the Gospel of Christ, so that, whether I come and see you or remain absent from you, I will hear about you, that you are standing firm in one spirit [i.e., united in purpose, and] contending with one mind for the faith of the Gospel [i.e., for the body of Christian teaching].

[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.

So, we should continue living by the same [standard] that we have [already] attained.

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.

According to

For even Christ did not please [just] Himself, but as it is written [Psa. 69:9], "The insults of those people who insulted you [i.e., God] fell on me [i.e., Christ]."

Live in a loving way, just like Christ loved us and gave Himself up [to die] for us as an offering and fragrant smelling sacrifice to God.

Each of you should not look out for your own interests [only], but also for those of other people.
