Philippians 4:8

Finally, believers, whatever is true, whatever is honorable and worthy of respect, whatever is right and confirmed by God’s word, whatever is pure and wholesome, whatever is lovely and brings peace, whatever is admirable and of good repute; if there is any excellence, if there is anything worthy of praise, think continually on these things.

We need to develop ourselves to the point that we can stay in peace no matter what is happening around us. To develop, we must practice focusing our thoughts on the list above. The mind is the battlefield, and the word is our sword. Speak the word, and God will be with us guiding our way.
