Jessie Penn–Lewis wrote in one of her books that passivity in church leads to captivity; and captivity results in death. Derek Prince had serious respect for Jessie Penn-Lewis.
Jesse Penn-Lewis wrote: (i) PASSIVITY OF THE WILL–There is a passivity of the will; the “will” being the helm, so to speak, of the ship. This originates from a wrong conception of what full surrender to God means. Thinking that a “surrendered will” to God means no use of the will at all, the believer ceases to (1) choose, (2) determine, and (3) act of his own volition. The serious effect of this, he is not allowed by the powers of darkness to discover, for at first the consequences are trivial, and scarcely noticeable.
(ii) PASSIVITY OF THE MIND–Passivity of the mind is engendered by a wrong conception of the place of the mind in the life of surrender to God, and obedience to Him in the Holy Spirit. Christ’s call of fishermen is used as an excuse for passivity of brain, for some believers say, God has no need for the use of the brain, and can do without it! But the choice of Paul who had the greatest intellect of his age, shows that when God sought for a man through whom He could lay the foundations of the Church, He chose one with a mind capable of vast and intelligent thinking. The greater the brain power, the greater the use God can make of it, provided it is submissive to truth. The cause of passivity of mind, sometimes lies in the thought that the working of the brain is a hindrance to the development of the Divine life in the believer. But the truth is, that (1) the non-working of the brain hinders, (2) the evil working of the brain hinders, (3) but the normal and pure working of the brain is essential, and helpful for co-operation with God. This is dealt with fully in Chapter 6 [of her book], where the various tactics of the powers of darkness are shown in their efforts to get the mind into a condition of passivity, and hence incapable of action to discern their wiles. The effects of passivity of the mind may be seen in inactivity, when there should be action; or else over activity beyond control, as if a suddenly released instrument broke forth into ungovernable action; hesitation, or rashness; indecision (as also from a passive will); unwatchfulness; lack of concentration; lack of judgment; bad memory.
