Demons? Sickness?

Satan is completely evil. John 10:10 says, "The thief comes only to steal and kill and destroy;" Some of the works of the devil are: sin, sickness, fear, death, depression, murder, temptation, deception, lust and rebellion. 1 John 3:8 tell us, "He who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil's work." Through Jesus we have victory of Satan and his works because Jesus made them of no effect. What can a person do if he believes it is God who sent sickness into his life to teach him something? He shouldn't fight against God so he allows the sickness to rob him of his health when he should be standing against it in the name of Jesus to be healed. We have to be able to recognize who is doing what in our lives to be able to react correctly according to God's word. Paul tells us that we are the determining factor in wheter the devil cna operate in our life or not. He says, "and do not give the devil a foothold." Ephesians 4:27. When we allow openings in our spiritual life the devil feels he has the right to take advantage of us in those specific territories. If we keep the doors closed he can't do what he would like to do. This is introduced in Genesis 4 :7 when the Lord says to Cain "If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must master it." God told Cain that Satan was crouched at his doorway, waiting to leap into his life. Cain had the choice and because he chose to open the door to jealousy, Satan led him into the murder of Abel. Sin is progressive. One thing leads to another until we find ourselves in big trouble. For that reason we must learn to close those doors and keep them closed before they develop into something harmful. Coach Rodden talked about how Christians cannot be possessed. Not everything is caused by demons. However, when it is an evil influence that is operating we will recognize and deal with it according to God's Word. We do not believe that Christians can be demon possessed, but they certainly can be attacked in their mind, will, emotions, and body. They can be troubled, pressed, buffeted,  harassed, depressed, obsessed, oppressed, in bondage and bruised. It is not God's will for us to live in constant bondage. John 8:36 says "So if the Son sets you free, you will be free indeed." John gives us the location of the devil if God is in us saying he is "in the world". In 1 John 5:18 God says that if we are not practicing sin the devil doesn't have the right to touch us.
