SOUL
A word with two distinct meanings in the Bible:
1. That which makes a human or animal body alive. This usage of the word soul refers to life in the physical body. The best example of this usage are those passages in the New Testament in which the Greek word for soul is translated as life. "For whoever desires to save his life [soul] will lose it," Jesus declared, "but whoever loses his life [soul] for My sake and the gospel's will save it. For what will it profit a man if he gains the whole world, and loses his own soul?" (Mark 8:36-37).

2. The word soul also refers to the inner life of man, the seat of his emotions, and the center of human personality. The first use of the word soul in the Old Testament expresses this meaning: "And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living being (soul)" (Genesis 2:7). This means more than being given physical life; the biblical writer declares that man became a "living soul," or a person, a human being, one distinct from all other animals.
