spir-it-u-al'-i-ti: The state of being spiritual in the higher use of the word. It is purely a religious term and signifies the state of a soul vitalized by the Divine Spirit and made alive unto God. It covers the entire range of man's faculties: intellect, feeling, will--all the attributes of personality.
The intellectual can be divorced from the spiritual, but the spiritual can never be divorced from the intellectual. If a man is spiritual, his intellect is touched with the divine life and comes under the power of the divine baptism. One word describes this mental quickening and illumination--"vision." "The pure in heart shall see God." Paul affirms (1Co 2:12-13) that the Spirit of God operates directly on the mental faculties, adjusting reason and intellect to the divine reason, and enabling man to think God's thoughts and discern His purposes, nature and will. The common use of the word "spirituality" limits it mistakenly to religious experience, narrowly interpreted, but as spirituality brings the intellect into harmony with the divine reason in every realm of mental action, it may be as manifest in science, art, philosophy, commerce and law as in religion.
The feelings and emotions are fertile soil for the spiritual life. Love is the beginning and end of true religion. Spirituality in the realm of the affections is that state of soul in which the heart with its holiest love is centered on God as revealed in Christ. The specific and supreme work of the Holy Spirit is to shed abroad God's love in the heart (Ro 5:5). Spirituality sets the affections on things above and brings the entire emotional nature under the regulating and redeeming sway of the Holy Spirit.
A spiritually-minded man is one whose will is set on God as well as his intellect and affections. In every fiber of his moral being, and in all the activities of his soul, he is under the guidance and dominion of the Holy Spirit. The affections present motives, the intellect estimates their worthiness, the will decides upon the course of action. When this trinity of mental operation--necessary to normal manhood--is under the sway of the Divine Spirit, man possesses spirituality, a state in which all the faculties of the soul are voluntarily and joyfully under the dominion and guidance of Christ's indwelling Spirit. When intellect, heart and will focus their energies reverently and affectionately upon Him, love--a passionate, ever-present, everdominant love--is the result. This is the triune sphere of the Holy Spirit's indwelling and activity, and the character of such a God-centered and Spirit-filled life is described by the exalted word "spirituality."
