'Often Satan injects pride into the believer's spirit, evoking in him an attitude of self-importance and of self-conceit. He causes him to esteem himself a very outstanding person, one who is indispensable in God's work. Such a spirit constitutes one of the major reasons for the fall of believers.' - Watchman Nee
I believe David Wilkerson is a true prophet of God. Maybe he is not recognized as such. Neither were some of the Israel prophets but they were sent by God as prophets notwithstanding. This is God's hour for heeding this great preacher of righteousness in our generation.
