Dear James, Human beings are both material and immaterial.
Humans are flesh as well as spirit and soul.
The Bible speaks of this diversity, while never losing sight of the unity of what it means to be a human. Thus the Hebrew Scriptures speak of a human as being a soul. Yet the Old Testament does speak of the soul as being that part of humanity that includes spiritual and emotional experience and expression, as opposed to the material body and flesh. Thus, while the Bible speaks of humans as being souls, the Bible speaks of humans having a spirit, not that they are a spirit. The Bible also speaks of other immaterial aspects and facets of what it means to be a human, including conscience, heart, will and mind.
