'Mind' in the Bible
Only [be sure to] lead your lives in a manner [that will be] worthy of the gospel of Christ, so that whether I do come and see you or remain absent, I will hear about you that you are standing firm in one spirit [and one purpose], with one mind striving side by side [as if in combat] for the faith of the gospel.
make my joy complete by being of the same mind, having the same love [toward one another], knit together in spirit, intent on one purpose [and living a life that reflects your faith and spreads the gospel—the good news regarding salvation through faith in Christ].
Do nothing from selfishness or empty conceit [through factional motives, or strife], but with [an attitude of] humility [being neither arrogant nor self-righteous], regard others as more important than yourselves.
Have this same attitude in yourselves which was in Christ Jesus [look to Him as your example in selfless humility],
All of us who are mature [pursuing spiritual perfection] should have this attitude. And if in any respect you have a different attitude, that too God will make clear to you.
