Few words in the New Testament have been subjected to more distortion than the word "Spiritual." Frequently it is used to denote what is little more than vague sentimentality. "Spiritual" in the New Testament refers to that which is of the Holy Spirit. The spiritual man is the person who is indwelt and controlled by the Holy Spirit and a spiritual state of mind is a state of mind that is produced and maintained by the Holy Spirit.
