The Hebrew nephesh is one of the most important and most misunderstood words in Scripture. In Genesis 2:7, God "breathed into his nostrils the breath of life, and the man became a living nephesh" — not "had a soul," but was a soul. The soul in biblical thought is not a separate immortal entity trapped in a body; it is the whole living person. Nephesh can mean throat, breath, desire, appetite, the whole person. The Greek psychē similarly means life, the animating principle, or the whole person. The biblical human being is a unified soul-body entity, not a soul imprisoned in a body (Platonic dualism). The soul matters because the person matters — wholly, not in parts. Jesus said, "Do not be afraid of those who kill the body but cannot kill the soul" (Matthew 10:28) — affirming that the soul survives death, but the full person awaits the resurrection.
SOUL, n. The spiritual, rational and immortal substance in man, which distinguishes him from brutes; that part of man which enables him to think and reason, and which renders him a subject of moral government. The immortal soul is the noblest part of man. The soul of man is an emanation from the Deity. In Scripture, soul is used for the entire person. The moral and emotional nature of man; as a soul of virtue; the soul of honor. Soul is sometimes used as an intensive. He cursed with his whole soul.
New Age spirituality has co-opted "soul" as a vague inner essence that survives death and may be reincarnated — disconnected from body, morality, or divine accountability. "Soul food," "soul music," and "soulmate" have further secularized the word into a general term for emotional depth. Meanwhile, scientific materialism denies the soul's existence altogether — there is only the brain, and consciousness is reducible to neurons. Both errors sever the soul from its biblical meaning: you are a soul, you don't just have one; you are accountable to God for what you do in your body; and the soul is not freed by death — it awaits resurrection and reunion with a glorified body.

"You do not have a soul. You are a soul. You have a body." (Often attributed to C.S. Lewis — captures the Hebrew holistic view)
"The soul is not what you have to save from your body — the whole person is what God is redeeming, body and soul, for eternity."
"'What shall it profit a man if he gain the whole world and lose his own soul?' — Jesus is asking about your whole person, your whole life, your whole self."
