When evil spirits are able to give visions, it is an evidence that they have already gained ground in the man, be he a Christian or an unbeliever. The "ground" being, not of necessity known sin, but a condition of passivity, i.e., non-action of the mind, imagination, and other faculties. This essential condition of passive non-action as the means of obtaining supernatural manifestations is well understood by spiritist mediums, clairvoyants, crystal gazers, and others, who know that the least action of the mind immediately breaks the clairvoyant state.
Believers not knowing these main principles can unwittingly fulfil the conditions for evil spirits to work in the life, and ignorantly induce the passive state by wrong conceptions of the true things of God. e.g., They may
1) in seasons of prayer, sink into a passive mental condition which they think is waiting on God;
2) deliberately will the cessation of their mind action, in order to obtain some supernatural manifestation which they believe to be of God;
3) in daily life practise a passive attitude which they think is submission to the will of God;
4) endeavour to bring about a state of personal negation, in which they have no desires, needs, wishes, hopes, plans, which they think is full surrender to God, and their "will" lost in God.
