Eph.5 Set your minds on things above, not on earthly things.
God says you are His child and you are more than a conqueror. He says you are an ambassador for Christ and you are to fight the evil around you. He also says you can do all things thru Christ and that all things are possible to those who believe. So trust God and use His might to strengthen yourself and be transformed by renewing your mind with the Word of God.
