Well here is the deal, if the response doesn't include the following, then its not a real answer:
1. Understanding why and how Satan fell from glory.
2. Understanding what sin is, how and why it exists, and the key to understanding this is in knowing why the tree that caused sin to enter the world was called the knowledge of good and evil.
3. Understanding why God chose his son, the word made flesh as the atonement for our sins before he even started the six day creation.
ok, so, Atheists are just Fundies who hate religion rather than loving it, at least in my book, and plenty of others have made the same observation, so, proceeding from that understanding, and accepting your premises here, imo it should first be realized that
you can't tell someone who knows everything anything, so voila you are basically done, unless you can respond with the proper
questions, which will open the door.
Now, from there, see that you are equ...you have the terminology that a Fundie will accept, but of course to an Atheist you will just be SiT and shutting the door again. So from there, see that all of the terms in your premises up there are translatable to IRL, to whit (off the top of my head here ok, i have given this part no thought whatsoever yet)
1. Understanding why and how people are not
at rest, even though their dog is likely happy as a lark; ego, iow, should do
2. Understanding what
making mistakes is, and how and why they exist, and how hard it can be for some ones to apologize for a mistake, no matter how they identify. The tree thing i would stay away from, unless/until you get that "tree" has symbolic meaning, as defined by Scripture; as does "Eating, drinking" etc. It was called "Knowledge" bc ego again, imo, or briefly, bc a child can be shown that
this sowing reaps
that, even though he is going to verify it a couple of times, and prolly keep checking it, bc after all parents are liars, basically, and kids are not stupid. It was called Tree of Knowledge because that was the fruit of eating from it; i think i repeat this lower from a diff angle
Conversely, a dog
cannot be shown that this reaps that, even though you can train one to do this or that, doesn't mean that they will ever understand or agree, just that they have made the association. Iow if you ring a bell and don't bring food often enough, they will eventually de-condition and stop drooling whenever you ring a bell. The dog has no
knowledge iow; it cannot make choices from information, or, since there is a sense in which they can, a better way to say that is a dog cannot change its mind about anything; it acts in its own interests, all of the time, even when it appears to be altruistic. A diff animal would provide better examples here
3. Understanding why those who would not care to hear about your understanding of God's Son might still be accepted, if they can merely confess, unto salvation, but transcribe the
salvation part. "i was wrong" is really all it takes. We religify
confession, and remove it to our churches (arm of government {501c3}, de facto courtrooms)(great place to learn Law) but confession is just "I was wrong, I'm sorry, what can i do now." which even an Atheist can appreciate, right
"why the tree that caused sin to enter the world was called the knowledge of good and evil."
bc that was what was reaped from eating of that tree, see. When you Biblically "know" another species in resistance to God's Instructions to animals, that we observe other animals rigidly adhering to, all other animals, you get hybrids, and in the case of the most evolved ones, you get frontal lobes, let's say, oh no duh it's the little pinecone deal, the kidney i think--and an ego--a separate "you"--to go with the eating; you get "knowledge of good and evil."
Of course the tree did not cause sin to enter, the eating of it did, and you likely do not accept my version of events here, but i made them up anyway, so make your own then, but see that we still have in our idiom/folk knowledge what Eve did, which was get tempted by a "snake" to (Biblically) "know..."
something, that was tasty to her, and caused (her, her progeny, whatever) her to "know," or "become intimate with," sin, iow feelings of guilt and shame come from getting a pinecone, too, that she never had to worry about before. and prolly the frontal lobes helped. free will is a great and terrible force to unleash
so, the point here is to use this as a possible model to converse with Atheists, if you were sincerely asking anyway lol. might help to remember that God divorced a whole nation of religious ppl and then sent them away right
then the kingdom will be taken from you and given to a nation producing the fruits of itiow if you are trying to 'convert' this Atheist imo you are wasting your time, if all you really need to do is understand (forgive) himpeace
