There is a devotion called Battlefield of the Mind. The title is representative of what we fight every day, our mind. In Philippians 2, it tells us to have the same mindset as Christ.
In your relationships with one another, have the same mindset as Christ Jesus:
Who, being in very nature God,
did not consider equality with God something to be used to his own advantage;
rather, he made himself nothing
by taking the very nature of a servant,
being made in human likeness.
And being found in appearance as a man,
he humbled himself
by becoming obedient to death—
even death on a cross!
We have been accepted in God by Christ. We are of one mind, that makes us like minded as Christians. The battlefield we face everyday can be guarded by God’s Holy Word. If we are in God’s word and allow it to flow through our thoughts and actions we are a testimony to others about His love and power. But, when we judge and slander we hinder that and stir up strife. We are to esteem others better than ourselves.
Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, not looking to your own interests but each of you to the interests of the others. Philippians 2:3-4
