1 Corinthians 2:10-11
There is a human spirit in which all of mankind shares. It is what, more than any other component of what we are, that enables us to be in God's image, and yet each person is a different personality. We are distinct from each other so that each person's spirit is also distinct. It is his own. Your spirit is yours, and my spirit is mine.
My spirit projects John Ritenbaugh. It projects my personality, my mind, my attitudes, my knowledge, my understanding, my wisdom, and my discernment - things that have come to me as a result of my experiences. Yours is exactly the same way.
What spirit goes back to God when we die? Is the spirit that goes back to God after your death different from the one that goes back to God from me when I die? Of course it is. Mine is mine, and yours is yours. In reference to God, His Spirit is Holy Spirit, but it is uniquely His. Are not He and the Son distinct from one another? They are.
