'Fighting' in the Bible

For though we may be living in the flesh, we are not fighting after the way of the flesh

(For the arms with which we are fighting are not those of the flesh, but are strong before God for the destruction of high places);

For I have a fear that, when I come, you may not be answering to my desire, and that I may not be answering to yours; that there may be fighting, hate, angry feeling, divisions, evil talk about others, secrets, thoughts of pride, outbursts against authority;
