Our security does not depend on our capability of "maintaining our beliefs". I believe the question to your answer is the same as the one I gave you before. God is the preserving factor. God is THE PRESERVATOR (good name for a movie

). I suggest all of us to study about the issue of "apostasy". 1 John 2:19 says who apostates that drifted so far as to become "antichrists", did so because they were not saved anyway. One may be an apostate from a religious system but I doubt anyone can "apostate" from God if one has ever been
of God. God will preserve them or make them persevere.
This second part of your question can be answered by declaring our total dependence upon God and belief in His promises, which,
again goes back to my original answer in the previous post. I don't see any need to go around proclaiming one's election or declaring "I am an elect" and I do not recall any command or even a suggestion in the Bible that we go around proclaiming such a thing. As a matter of fact, as a rule, people who go around making claims about their stance in God, based upon something that they feel about themselves, are likely the ones you assume will eventually backslide into apostasy.
Now, probably, using the Bible I will be able to contribute to a possible answer to your questions: The parable of the Prodigal son. One of the richest teachings of Jesus (if there is any that is not as rich) because it tells us of:
- One who was a son with an inheritance guaranteed
- One who misued his heir status and departed from the Father
- One who backslid into a world apart from the Father squandering his inheritance to the point of living as if he was not an heir
- One who decided to return home declaring no longer to be worthy of being called a son by the Father
- One who encountered His Father by the wayside, waiting for him
- One who received the family ring and new robes
- One who was cleaned by the Father before being reintroduced to the family so his dirty ways would not be exposed
- One who was dressed by the Father before being reintroduced to the family
- One of whom the Father wanted all to rejoice.
He was a son before (elect); he backslid; he returned; he thought no longer to be a son; he was received as a son as if he'd never left.
All of the above was guaranteed by the Father.
Using your words and applying it to the parable: He knew he was a son (elect) when he
was not in apostasy; He thought he was no longer a son when in apostasy; He was received as a son even as an apostate. In the interval, between his departure and his repentance, THE FATHER was along the way waiting for his return.
The Father was the guarantor and the sustainer of his sonship (election).
Whether we know or not that we are sons of God (elect), it is up to the Father. His Spirit bears witness with our spirit that we are His sons. That makes us return to Him as the mystical relationship of the Prodigal son and his Father made him return to him in repentance. The Father will draw back His sons (elect)! I believe you would agree with me that no religious stance, appearance nor practice can be proof above and beyond shadow of doubt that one is an elect. It is only the witness of the Holy Spirit and is the Father who predestinates us, calls us, justifies us, and glorifies us.
I hope I answered your questions.
