“The early Christian philosophers adopted the Greek concept of the soul’s immortality and thought of the soul as being created by God and infused into the body at conception.”​—The New Encyclopædia Britannica (1988), Volume 11, page 25.

“The soul that sinneth, it shall die.”​—Ezekiel 18:4, King James Version.

Regarding the creation of the first human soul, the Bible says: “Jehovah God proceeded to form the man out of dust from the ground and to blow into his nostrils the breath of life, and the man came to be a living soul [Hebrew, neʹphesh].”​—Genesis 2:7.

The Hebrew word neʹphesh, translated “soul,” means ‘a creature that breathes.’ When God created the first man, Adam, He did not infuse into him an immortal soul but the life force that is maintained by breathing. Therefore, “soul” in the Biblical sense refers to the entire living being. If separated from the life force originally given by God, the soul dies.​—Genesis 3:19; Ezekiel 18:20.

The doctrine of the immortality of the soul raised questions: Where do souls go after death? What happens to the souls of the wicked? When nominal Christians adopted the myth of the immortal soul, this led them to accept another myth​—the teaching of hellfire.
