Soul and spirit are interchangable. Man's sin is thinking he could be like God knowing everything, trying to build a tower to heaven, marveling in his own works instead of God's works.
Soul and spirit are interchangable. Both are same thing. The soul is your heavenly spirit which has a free will. Out of body experiences are your soul leaving your body. You know nothing about it, so shouldn't speak about it.
Spirit is the eternal you, soul is the continuously corrupted you that you have to purify. Still both coexist and are both you. Soul is just your free will, spirit is your existence.
