What is a Soul?
The answer is in several places in Scripture.
SHORT ANSWER: Soul is the combination of spirit and flesh(body).
1) James 2:26
"For as the body without the spirit is dead, so faith without works is dead also."
2) Genesis - God breathed (his spirit) into the flesh and it became alive.
The term 'soul' is also referred to as a 'living being' or 'creature.'
Genesis 2:7 "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 soul."
