Part of working this out (the balance between Creation and Evolution) is identifying how we come into agreement, with what was already professed to have been coming. We are predetermined, in God, that can't change; but our agreement with how we are predetermined, does change. This is a mystery; we will be known as we knew ourselves in God. Therefore, if it is our manner to develop integrity - whether we believe in God or not - then when we are revealed in God, we will be revealed to be one that developed integrity. Evolution can't change that - we will always be the one that developed integrity and shared our integrity in God. The world hates this, but there is nothing that can be done about it, if we surrender to the One for whom all integrity can be made. Jesus is that One.
So then, if we are known to reveal integrity, and we reach Heaven and dutifully share that greater integrity, more integrity will be found. This is too late for Evolution to do anything other than be what it was, until it is next to nothing. If people still want almost nothing, despite the opportunity to develop integrity with me, the one that develops integrity need not condemn these people, their having almost nothing will put them in want of something, which is down to their word or the Devil's, whichever it is that has the greater sin. Therefore as Jesus said "My word will judge them" so they will be judged.
What this contest with the Devil doesn't change, is that the integrity that is revealed, is revealed as a choice - a necessary part of the puzzle, as far as Evolution is concerned. If Evolution ignores the choice, the Evolution is not true. That is a choice. What the Devil can do about that, is for anyone to guess, being a commitment to sin, regardless. So it will be, at some point, that the Devil will covet choices like it, that he may create an imitation. This is just the inevitability of the contest between Heaven and Hell. It will not be necessary to define or determine integrity again, integrity will already be established. Neither, if the one that develops the integrity trusts Jesus, will it be possible to bring that one into disrepute. Evolution of integrity, will have to be of the choice granted by integrity. This is an immutable fact, in no way does the integrity of it have to be more established in the way of Evolution, other than to say, that interacting with other values may affect the balance of integrity remaining - that it remains in some degree, will be beyond question.
I hope this has provoked your thought, that you are beginning to wonder "what manner of integrity, do I want?" "do I have the right balance of integrity?" - I myself struggle with these questions, and am constantly trying to work out, where the balance of integrity is best "committed to". I could go on about the relationship between commitment and integrity, but I will leave it there.
God bless.
