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 strengthenyourself and be transformed by renewing your mind with the Word of God.
God says to watch what you are thinking and to renew your mind with the Word of God. God says :Do not conform to the pattern of this world, but be transformed by the renewing of your mind. (Renewing with the Word of God)
Depression is a spiritual attack on the mind. It occurs when you feel a lack of hope. Satan will use this as an opportunity to attack your mind. He tries to discourage you by telling you about all of your failures, sins, wrong choices and bad relationships you have had.
