Well, if you’re referring to “no one will snatch them..” you have likely heard the rebuttal: that this is of course true. But we can separate ourselves. Unless you are a Calvinist, you believe in free will. God does not force us to love Him now or in the future come what may; we may change our minds and hearts as many have.
Now, I still have the question for you, never answered, from a while back:
You said you believe all your future sins are already forgiven whatever they may be. Does this include blasphemy against the Holy Spirit?
Jesus said that blasphemy against the Holy Spirit is the unforgivable sin.
Tell me, can a believer who has the Holy Spirit living in him blaspheme the Holy Spirit? Can he say that it is a demon living in himself?
The context in which Jesus made that statement was when the Pharisees were attributing to Satan the clear works of the Holy Spirit that Jesus was doing. They were stating that Jesus was demon possessed for doing miracles only God could do.
