"My people are destroyed for lack of knowledge" (Hos. 4-6) is certainly applicable to our day. Christians nowadays generally are lacking in two kinds of knowledge: (I) a knowledge of the conditions by which evil spirits work; and (2) a knowledge of the principle of spiritual life. Ignorance here is furnishing Satan and his evil spirits an incredible advantage and is inflicting enormous harm on the church of God. What grieves our hearts is that, even as folly is prevailing, Christians continue to boast of their familiarity with the Bible and of the abundance of their experience. They do not realise that their much so-called knowledge is mere human reasoning, quite devoid of usefulness. Humility before the Lord and eagerness in seeking the revelation of God's truths are almost unknown. While boasting in the richness of their knowledge, they themselves sink into the very quicksand from which they can neither extricate themselves nor rescue others. It is indeed a most dreadful scene.
THE LAW OF CAUSE AND EFFECT
For each and every thing God has created there is a law. All actions are governed by laws. Hence evil spirits also operate according to definite laws, one of which is that certain causes will produce certain effects. Now should anyone fulfil the conditions for the working of evil spirits (whether be fulfils them willingly, such as the witch, the medium, or the sorcerer-or unwittingly, such as the Christian), then he has definitely given ground to them to work on him. Notice that the law of cause and effect is involved here. Fire scorches, water drowns: these are laws: none escapes scorching if he falls into fire, nor can any escape drowning if he jumps into water. Likewise everyone who meets the requirements for the operation of evil spirits will be harmed by them. Hence the same law of cause and effect is operative here. It pays no heed to whether one is a Christian or not; once the conditions are met, the evil spirits do not fail to act. just as a Christian cannot avoid being scorched or drowned if he falls into fire or water, so he cannot escape the danger of being hurt if he ignorantly supplies the prerequisities for the working of evil spirits. The fire scorches everything put into it; the water drowns all who are immersed in it; and evil spirits attack all who give them ground. One will not escape simply because he is a child of God. If he provides the enemy the opportunity, he will not hesitate to assault him. What, then, are the conditions for the working of the enemy? What facilitates this malevolent working? This is the crucial question. The Bible characterises such conditions as "Place" (Eph. 4.27 ASV) or "opportunity" (RSV). It can additionally be denoted as "ground." It means any portion of empty space marked off in man for the evil spirits. This place or ground constitutes their foothold. The degree of invasion is determined by the degree of the foothold. The evil spirits will commence to penetrate into any man, be he "heathen" or Christian as soon as he has obtained a footing in him. Whatever affords the evil spirits an opportunity or a foothold by which to attack or invade may be termed as "ground." If ground is given, invasion is unavoidable. The particular cause brings in the particular effect. A Christian who yields ground to evil spirits and yet envisages himself to be beyond attack has been gravely deceived already by the enemy. Nee
