Faith in the Name.

And these signs shall follow them that believe; In my name shall they cast out devils;”       
Mark 16:17(KJV)
     
Every Christian has the same authority in the Name of Jesus. So the Name of Jesus doesn't work because one person is more anointed than the other, no. Anointing and authority are two different things. The Name of Jesus works not because of the anointing you carry, but because of your faith in the power in the Name.

Matthew 7:21-22 says, “Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?” Notice that the Bible says that these people prophesied, they cast out devils and they did many wonderful works in the Name of Jesus. They had faith in the Name of Jesus and they performed real miracles in that Name, but they lived unrighteous lives, which disqualified them from inheriting the kingdom of God.

This is why Jesus said about them in Matthew 7:23, “And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.” So, Jesus knew they were working iniquity, yet they were able to do all the things they did in the Name of Jesus. How come that was possible? You would better understand this when you understand  that the legitimacy of an authority is not gotten from the one on whom the authority is delegated to, but instead the legitimacy of any authority comes from the source from which the authority is gotten.  This is why Peter said in Acts 3:12, “… Ye men of Israel, why marvel ye at this? or why look ye so earnestly on us, as though by our own power or holiness we had made this man to walk?” The Name of Jesus will work for you because of your faith in the power vested in that Name.

Confession.
I have authority in the Name of Jesus because of my faith in the authority vested in His Name. Therefore nothing shall be impossible unto me in Jesus Name.
