Where do wars and fights come from among you? Do they not come from your desires for pleasure that war in your members?
1 Thessalonians 3:12-13
12 And may the Lord make you increase and abound in love to one another and to all, just as we do to you, 13 so that He may establish your hearts blameless in holiness before our God and Father at the coming of our Lord Jesus Christ with all His saints.
