Hmmm. It seems we are on the same page regarding the likely different sense in which the word is used in Scripture. :)
I think, like you, many people use the terms interchangeably or synonymously. One thing that I'm not clear about is the significance of the expression the spirit returns to God.
I can't recall if I recently asked you or
@RLT63 (maybe it was MatthewG? ) about their being Judgement Day everyday. Correct me if I am wrong but my understanding is on Resurrection/Judgement Day we will awake standing before Judgment with no awareness of time from our death until then. So, what is this about the Spirit returning to God?
This actually brings up a theory that I have, that is fully supported by Scripture, and that most simply cannot endure because there is zero teaching on it outside of the Bible.
That theory is that ONLY believers, who have the Holy Spirit, are resurrected.
Look at the points you made. The Bible says the spirit returns to God, right? Ok, we also see that Jesus refers to those who have not the Spirit as
dead.
"Let
the dead bury
the dead."
Luke 9:60
We could Biblically conclude that God is
in the heavenly realm (despite the omnipresent Truth as well). When we die, our spirit goes to be with God, IF it has life.
How does our spirit obtain life? Jesus says in John 6 that it is the ingesting of His Words that nurture the spirit inside of us; that quickens us, that gives us spiritual LIFE.
John 6:63, 68
Therefore, those who have not the Spirit, have nothing to nurture with God's Words and have
no life. They are dead.
As far as the resurrection you referred to, that is the reunion of our spirit with our physical bodies. If all that I have related is True, that is not possible for the unsaved/unbelieving.
Which has
huge implications for some of the most common false doctrines.
