ANOINTING

"Thus Esau despised his birthright."       Genesis 25:34

Adam rejected God's anointing, Esau rejected Isaac's anointing, Judas Iscariot rejected Jesus' anointing and the same spirit of rebelliousness has continued to be passed on from generation to generation. 
Those who turn their backs on the anointing of the Divine are subject to Satan's power. You can't have God as your Lord and the devil as your lord at the same time. You are either a child of God or a child of the devil. You are either a temple of the Holy Spirit or a vessel of the devil.
This is why most believers are troubled, unsuccessful and possessed by demons. They have accepted Jesus as their Savior but have rejected Him as their Lord.
