The Root of the Righteous by AW Tozer
The human heart is heretical by nature, and unless well instructed by the Scriptures and fully enlightened by the indwelling Spirit it is sure to introduce some of its own notions into its religious beliefs and practices. It may, for instance, confuse the fervor of the Spirit with the heat of the flesh, and mistake the scintillations of the overheated imagination for the glow of the true Shekinah. And this can be extremely dangerous, especially when it is found among religious leaders. It is true that Ezekiel on one occasion went in the heat of his spirit; but there is no hint that his mind was anything but calm, for he said also that the hand of the lord was strong upon me. The steadying hand of God prevents the fever of the human spirit from affecting the critical faculties and leading to extreme and unwise conduct.
