Once saved always saved

[CrowCross]

The Lord God Almighty, possesses the spiritual “Gift of Salvation.”

It is His Gift…to OFFER…to whom He pleases.
Offered TO Animals? No
…WHY NOT?
Because Animals do not, can Not SIN.
…Because they have Not the capacity TO Distinguish a Truth from a Lie.

Offered TO Angels? Yes.
…WHY?
Because Angels were Created with…
* Everlasting Life.
* The Truth of God IN Them.
* FREEWILL to Remain With God or Reject Him.

I'm curious about this section...

Do you have a verse or two that suggest fallen angels have the gift of salvation offered to them?
