Lets look at it from the point of dreams. When one sleeps and slide into dreams, is it with his physical body or another body? Definitely not with the physical body. Therefore, there is also a spiritual (ghost) component of man. The Christian bible account of creation says that God is a spirit and created man in his image and likeness.

Genesis 1:27 Ref. So God created mankind in his own image, in the image of God he created them; male and female he created them.

When man dies the bible has this to say, " and the dust(body) returns to the ground it came from, and the spirit returns to God who gave it.
Ecclesiastes 12:7.

Hebrews (:27 say this " And as it is appointed unto men once to die, but after this the judgment:" After what?? After the body is dead, the spirit which is the real man will face judgement. Time will fail me here to continue on this subject. Maybe we may have to steemit again. Cheers
