Ephesians 6:10-12 A final word: Be strong in the Lord and in his mighty power. Put on all of God's armor so that you will be able to stand firm against all strategies of the devil. For we are not fighting against flesh-and-blood enemies, but against evil rulers and authorities of the unseen world, against mighty powers in the dark world, and against evil spirits in the heavenly places.
I think that this verse is so important to put into our storehouse of verses. We need to call on this verse whenever we are being mistreated by someone. The first thing I thought of is that when someone is not treating me right, it is not them, it is Satan and his evil. If I treat that person with goodness and kindness and love no matter how they treat me them I have not let Satan win. I have done what God ask us to do.
Luke 6:32 says that even sinners love those who love them. We are called to love, even the unlovable. We are called to be kind to the unkind. We are called give to the selfish. We are called to walk in love with everyone no matter how we are treated. When someone is being unkind... the loudest voice in their head is Satan... our actions need to help them be able to hear God.
