I think you are right anon. I think once given permission, that spirit of God "locks in".
What did Jesus say ... I think that not one was lost once in the palm of his fathers hands.
I was more talking about man having the free choice of who's spirit would have permission to reside?
And, while were on the subject, I hear they often tell their satanists, that God does not want them, so, no sense in asking anymore?
They lie about this.
Only the spirit of God locks in.
I think the demons and such evil can always be rejected, at any time. Which is probably why they lie about it.
