And life is contemporaneous with that God-given breath: "All the while my breath is in me, and the spirit of God is in my nostrils." Job 27:3.
If God decided to withdraw His life-giving spirit from the world, everyone would die at once: “if He set His heart upon man, if He gather unto Himself His spirit and His breath; all flesh shall perish together, and man shall turn again unto dust." Job 34:14-15.
The spirit returns to God because it came from God and because God gathers it to Himself. There is nothing here to indicate a disembodied consciousness."
