Was Adam and Eve’s sin the same as Lucifer’s?
In essence, yes. Lucifer
rejected God’s plan. He
chose to be cast from heaven rather than stick around as man took a higher place in heaven than him.
Eve and Adam
rejected God’s plan for them. They
chose to eat of the fruit which God specifically told them not to eat, thus rejecting the notion that they are not equal to God.
If so, does that mean that some of God’s creation (angels, humans if they’re not the same), will always reject him?
No. It only means those of God’s creation who possess free will will always have the opportunity to reject Him.
If He has created other life forms in other galaxies, some will reject him? Is this a given?
Only if they were given the gift of free will from God, their creator.
If its called free will, I’ve answered my own question. Does that mean that by creation, God knows that some will reject Him and be damned?
Well that’s one of those great mysteries and paradoxes because God is omniscient and not constrained by time or space so yeah, He knows who will reject Him, and supposedly who’s damned.
However, God is love and where there is love there is hope. There are many scripture stories and stories of the saints where we learn that God provides the means by which each and every one of his creatures can be redeemed, should they choose to accept His gifts. In our own daily lives we can find what some call ‘happenstance’ or ‘coincidence’ events whereby a person, place or thing, for some unknown reason, moves us to divert ever so slightly (or sometimes 180 degrees) from the path we intended to take, only to find that by veering off that path our life is changed. I think this is what we call
‘Divine Providence’…the hand of God working to nudge us toward the path closest to Him despite our willful intent to try to ignore Him.
Why would He create, so that some would be damned?
He creates out of love for us. Love is meant to be poured out, not contained.
Why repeat what He has already done?
I don’t understand the question. What did he already do that you think is being repeated?
I think, as I’ve stated above and in other posts, that God created conscious beings, angels, souls, us (one and the same) ONCE ! God has given the original and only conscious beings a second chance. The second chance is the universe. In our case currently, planet Earth.
He certainly created this universe we’ve come to know ONCE. But we humans and these galaxies are not finite objects. You and I are
still being created with every breath we take, with every thought which comes into our minds, with every emotion evoked within us. The planet is still growing (and dying, yes), but the point is it is an ongoing process. He’s not done with any of it yet.
Why does evil/sin exist? All it is, is the rejection of good (God). We are the reason it exists.
I agree we are the reason it continues to exist, but I do not believe it is ‘just’ the rejection of good.
Remember that Satan manifested himself as a serpent to plant the seed of doubt into Eve’s mind. She and Adam did not turn from God all by themselves, they were manipulated into it.
So, evil, manifested and manipulated by Satan and his minions, is a force to be reckoned with for certain. That aspect of evil is not just you and me rejecting God, it really is other forces actively working to pull you and me away from God. The same forces which will, until the end of this time, continue to gnaw away at the Catholic Church from within and without.
