"As with "soul," "spirit" can be said to depart at death (e.g. Ps. 78;39; Job 17:1; Isa. 57:16; Eccl. 12:7; Lk. 23:46; Acts 7:59; Ps. 104:29; etc.); the disembodied dead are designated as "spirit" (e.g. Job 4:15; 1 Peter 3:19; Heb. 12:23) - indicating a living selfhood. Consequently "spirit" cannot be taken from scripture to support a doctrine of immaterial substance in man; even a passage so strongly positing discontinuity between "spirit" and bodily flesh as Col. 2:5 cannot be read to mean a man's immaterial substance left his body to be elsewhere! "Spirit" can certainly designate man's inner, private life(e.g Dan. 7:15; 1 Cor. 2:11), and death can be seen as the loss of "life-breath" (="spirit"; e.g. Ps. 104:29), and the dead can be affirmed to still have self-conscious life by being called "spirit" (though very infrequently in scripture to be sure), but nowhere does scripture imply that man is a dual substance which divides as he dies (unless you read the Bible through Cartesian glasses). "Spirit" means life (centered in the breath image - just as "soul" is life centered in the blood image)."
