I see it different from Christianity on average, and I'm a Christian.
I looked into Vine's Expository Dictionary about the Hebrew word for soul, and it is that the soul is the "Seat of Judgment". The heart is the "Seat of Emotion". So in that way, I adopted that view. I do not use soul and spirit interchangeably like most Christians I met do.
The spirit is in everyone, they are born with their spirit. To me it represents what give us life. The English word "breath" is sometimes used in the Bible depending on the translator only. The same word for breath is also spirit. The spirit is the eternal part of us. We, being corrupted, fail to understand the eternal part of ourselves, and we place all importance on the temporary part of ourselves; the body is temporary, and we relate to the lesser part of our self most.
