One of the problems of  Christianity is that  Christians do not know who  they are, whom they belong to and  what He did  for us. I believe this is  the reason Paul prayed that our  eyes of understanding be opened  that we might be able to  comprehend what God gave to us  in Christ Jesus.
The Police man knows who he is. In his uniform he’s not afraid to stand  in front of a two-ton trailer to flag  it down.
When you know who you are no  one can push you around. Daniel  said that those who do know their  God shall be strong and do exploits (Dan. 11:32b).  Only people who do not know who they are, become  afraid of witches, demons and  powers of darkness.
God, speaking through James says “resist the devil and he will flee  from you.” (James 4:7) The devil  can only flee when he knows you  know your rights as a child of God.  That was exactly what happened  between the demons and the  seven sons of Sceva. They were  aware that Paul knew his rights,  but the sons of Sceva were only  living by hear-say.
Stop living by what your pastor  said; it could be dangerous! The  sons of Sceva lived by what  somebody preached, not what was  opened up or revealed to them. Get to know  who you are, what Christ did for  you and what God gave to you. To  do so you need to:
(1) Make up your mind. Are you  truly on God’s side? A citizen of  heaven? No, not being a church  goer! In 1 Kings 18:21, Elijah asked the chosen children of God; the  Israelites why they were  undecided. Undoubtedly they were  children of God but were not “Wholly” with Him. They were  hopping between two opinions. In  Revelations 3:15-16, Jesus warned  against spiritual coldness; a  luke-warm attitude that has fanned Christians to be neither here nor  there. Make up your mind. If God is  God, serve Him with all of your  heart.
(2) Stop thinking and acting as a  worldly citizen. Kingdom ways are  God’s ways. And God’s ways are  not our ways. That is why we are  told to be renewed in our minds, in  our way of thinking; not as the  world but as children of God. (Rom. 12:1-2) Negative thoughts should  not be allowed to dwell or take root in our hearts. We are to pull them  down, uproot them (2 Cor. 10:4-5)  and replace them with “whatsoever things are true,  whatsoever things are honest,  whatsoever things are just,  whatsoever things are pure,  whatsoever things are lovely,  whatsoever things are of good  report, if there be any virtue, and  praise to God.” ( Phil. 4:8)
(3) Speak as a citizen of heaven.  Job was reminded by his friend  Eliphaz that its no one but his own  mouth that condemns him (Job  15:6). Jesus equally tells us that  our words justify or condemn us.  Watch what you say! Speak only  the word of God when the enemy  backs you up on a corner.
(4) Disconnect or unplug from  some friends! This could be very  hard especially as we are creatures of emotions. Abraham carried his  nephew and did not hear from God  till they were separated. It is said “show me for friend and I’ll tell you  who you are”. You are defined by  your choice of friends! Have a  standard of choosing who your  friends are! Jesus said (John 15:14) “Ye are my friends, if ye do  whatsoever I command you”. Who  told you you can’t do without those  people? Pull out!
To move closer to God this year,  and to have a stronger voice in the  Kingdom, fellowship with the  believers, trust in the Lord and see  Him turn things to your favour! Even the devil shall bow!
