In our earthly life, a lost soul is someone who has no direction in their life, no apparent purpose. They have many acquaintances but few friends. Those who do know this person think them a little strange, or socially awkward. Perhaps some of them are psychopaths, people who lack empathy.
The soul is the body or person as a whole: The one who created the human body tells us what the soul is--. In the Bible, soul is translated from the Hebrew nephesh and the Greek psykhe. Bible usage shows the soul to be a person or an animal or the life that a person or an animal enjoys.
