Qualities of the Holy Spirit: The Spirit of God does not die

1 Corinthians 15 vs 44

It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.

Man is made of a physical body and a spiritual body.
At the death of every man, only the physical body dies. The spiritual body either goes to heaven or hell.
When a man dies, the physical body goes to the grave but the spiritual body is immortal.
On the judgement day, It is the spiritual body that is judged.
And that is why the Bible tells us not to be afraid of the one who can only kill the physical body and not the spiritual body.
