Remember - the devil is NOT for you. He is and will always be against you. Don't believe his lies. God is for you and will ALWAYS be for you! For the truth is in Him and His word. Again, He holds the only VICTORY that matters. Believe that.

You belong to your father, the devil, and you want to carry out your father’s desires. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies. - John 8:44
