Christians today generally lack two types of knowledge: the knowledge of the conditions through which evil spirits operate and the knowledge of the principles of spiritual life.
The law of cause and effect
For each of the things that God has created there is a law. Evil spirits also operate according to definite laws. Now if someone offers the conditions for the operation of evil spirits, then certainly they have yielded ground for them to operate. This is the law of cause and effect – evil spirits will harm whoever fulfills the requirements for their operation. Fire burns everything that is placed within it; water drowns everything that is immersed in it, and evil spirits attack everyone (even the children of God) that yields ground to them. Demons begin penetrating the life of any person, as soon as they obtain a basis to support their operations.
Simply put, any ground that a Christian yields to demons is sin. Every sin provides ground upon which they can operate. There are two types of sin: positive and negative. Positive sin is that which a person commits: the hands do bad things, the eyes contemplate evil, the ears listen to ungodly voices and the mouth speaks impure words. However, the Word of God also says that the omission of some things is sin (James 4:17).
The believer’s passivity constitutes the sin of omission that yields ground to demons. The lack of use or the misuse of any part of our being is sin in the eyes of God. We must use all of our abilities and gifts because when we do not the devil gains access to each one of them.
The error of passivity
Sin and passivity precede enemy invasions among pagans and even among Christians. The passivity of a Christian springs from the lack of use of his various talents. He has a mouth, but refuses to speak, waiting for the Holy Spirit to speak through him. He has hands, but does not use them, because he expects God to do this. He doesn’t use any part of his being, but waits for God to move him. He doesn’t consider himself completely surrendered to God therefor; he doubts his own motivation and no longer uses any part of his being. In this way, he falls into inertia and opens the way for deceit and demonic infestation. Christians think that union with the will of God will annul their own will and transform them into puppets. This becomes a means and an invitation for the enemy to enter.
The foolishness of the believer
We must actively exercise our own will. Jesus showed this in John 7:17, which says, “If anyone wills to do His will” and John 15:7, which says, “You will ask what you desire”. We enjoy a free will and God never undermines it. He expects us to obey him, but at the same time, he respects our personality. Satan however, has no way to usurp any part of man without his permission, whether conscious or not. Satan needs to gain the permission of the Christian, but the Christian will never give it to him. For this reason, the devil is forced to use deceit in order to gain the permission of God’s people before he comes into their lives.
The operation of God and that of Satan are different. God invites man to choose actively, consciously and voluntarily to obey his will, so that his spirit, soul and body may be free. Satan forces man to be his passive and captive slave. God is pleased when His people desire what He desires.
Here is the order of the process that causes many Christians to fall into the hands of demons:
After following all of these steps, the deceit deepens, resulting in a prison of alarming proportions. A person in this state prefers to be guided by circumstances, rather than being free to choose his own direction, because he considers making a choice too tiring. In such a condition of inertia, deciding even a small matter becomes a tremendous task. The victim seeks help in every direction. Such a person feels quite bothered by not knowing how to deal with his daily business. He seems to be hard-pressed to understanding what people tell him and to remember something is extremely painful. Such a believer waits for help, for an exterior push. Are we suggesting that such a believer does not like to work? Not at all! Because when an external force pushes him, he is capable of working, but as soon as the push ceases, he stops in the middle of his work, feeling as if he has no strength to continue. This believer does not conclude his tasks.
Because his will is so passive and unable to operate, generally evil spirits guide him to situations where he must exercise his will in order to embarrass him and subject him to ridicule. These evil spirits instigate many difficulties in order to exhaust the energy of the believer. Sadly, many have no strength to protest or resist. Demons are able to take advantage of their victims because they fall into ignorance and deceit and from deceit to passivity and from passivity to the sufferings of profound imprisonment. Even so, many believers do not discern that God does not bring about such situations, therefore, they continue in their passive acceptance of them.
Do you not know that to whom you present yourselves slaves to obey, you are that one’s slaves whom you obey, whether of sin leading to death, or of obedience leading to righteousness? (Romans 6:16)
If we offer ourselves to God and serve him merely with our mouths, but in practice subject ourselves to evil spirits, then we will not be able to escape being slaves to their will.
