John Owen – Spiritual Mindedness – Chapter 7

In your thoughts of Christ, be very careful that they are conceived and directed according to the rule of the word, lest you deceive your own souls, and give up the conduct of your affections unto vain imaginations.
Spiritual notions befalling carnal minds did once, by the means of superstition, ruin the power of religion.
