Well with regards to point 1), numerous atheists have come to the conclusion that eternal life is real without having become Christian believers, just accepting that there is an ultimate being, as have numerous members of other belief systems, without necessarily abandoning their beliefs.
Point 2), you are assuming that Paul was supporting a physical resurrection which is not necessarily true. Resurrection was widely accepted at the time with numerous people believed to have been resurrected. Finding their physical remains was not an issue.
Point 3) moral free will might well be at least partially an illusion. Morality can be supported by games theory as the winning approach without regards to any divine being. Further, the scriptures can be understood without reference to morality but rather in terms of relationships.
Point 4) if these humanoid type creatures were to recognize that being created in physical form reenforced the likelihood of relational issues and that a return to a spiritual existence could resolve the issue then they would have no need for a salvific history.
Point 5) God is quite capable of doing so and has done it with select people. Why He does it with only certain people and not everyone is not totally clear, but a plausible case can be made for not such a reveal, the bigger question is why the occasional one.
Point 6) is a theoretical possibility, but depending on how it was accomplished, might fail anyway.
You will note that I am not interested in blind faith or a lucky guess. I have analyzed the various atheist beliefs into these four:
1. Humanism has three denominations including: egoism (meaning is self-dictated), elitism (“might makes right”) and popularism (“the majority rules”). These isms implicitly recognize that souls are forced by the structure of reality to choose what to believe; humans are volitional beings, paradoxically forced to make free moral decisions. However, this choice or affirmation does not necessarily mean people determine or create truth ultimately. (Is mankind the pinnacle?)
The truth of egoism is that each individual is responsible for his/her choices (but to whom; is there a Higher Authority?). The truth of elitism is that the ruling class of people has political power over those who are governed (although a superhuman Governor of the universe may exist). And the truth of popularism is that in a democracy the majority may be the governors (however, this does not mean its decisions are objective or right). In short, selfish
people may be I-dolatrous, but they cannot become God.
2. Karmaism, (found mainly in Hinduism/Buddhism), has a doctrine of reincarnation according to one’s karma or performance of good and evil deeds. This belief provides a rationale for universal morality (a UMI), but its fallacy may be assuming that the ground of meaning is impersonal, merely natural or even subhuman. Although there are occasional claims by someone to have memories of previous lives, if karmaism were true one might expect that everyone who was a sentient human being in the previous life would remember much of it. Thus, I find insufficient evidence for karmaism (reaping what is sown naturally).
3. The adherents of
naturalism posit that humans instinctively accept the validity of morality or of acting in accordance with a reciprocity principle or the “golden rule” (do unto others as you would have them do unto you, cf. Matt. 7:12), and they are satisfied with whatever meaning can be derived from this earthly existence. The problem with this view is that humanity has also had a proclivity toward evil throughout history, so there is no basis for saying the negative force toward others is not equally valid and for mandating a universal golden rule or moral imperative. Logically, all it can offer is a “pyrite suggestion”. Morally, it merely continues KOTH.
4. Pantheism or belief that nature is god and
polytheism or belief in many gods envision a vitiated or diminished divinity and thus are tantamount to atheism. Also,
deism says God created the world but does not interact with it (as though He died), which amounts to practical or functional atheism. The cry of Jesus on the cross, “My God, why have you forsaken me?” (in Matt. 27:46) expresses feelings in accord with this view, while the resurrection of Jesus (Matt. 28:5-7) provides hope that such feelings do not match the facts.
The choices involved in making the second watershed decision (the ground of meaning/morality) correspond to the following questions: For a humanist, “Is there any reason I should not be selfish?” [No/Yes, depending on how you feel or what the rulers decree or how the majority votes.] For a karmaist, “Does how I live ultimately matter?” [Not unless you can remember previous lives.] For a naturalist, “Does instinct negate volition? [If not, then why is evil/hatred not equally right or existentially lawful?] And for a theist, “What does God desire?” [That depends upon what message or revelation is from God.]
Which option and opinion is best or most true? Answering this question involves understanding how truth is acquired (epistemology). Some knowledge is gleaned directly from personal experiences and is available to all who seek to know the truth with an open mind (like Socrates or Buddha) by means of reflecting or meditating on experiences logically. The apostle Paul indicated the world reveals God’s “invisible qualities—his eternal power and divine nature” (Rom. 1:20) and that conscience indicates “the requirements of the law” (Rom. 2:15).
A second possible way of obtaining knowledge is by learning from the insights or inspiration of others. Divinely inspired knowledge was claimed by Jesus (in John 14:9-11), Paul (in Gal. 1:11-12 & Tit. 1:1-3). Insights could be a combination of reflection and inspiration, perhaps taught by God’s indwelling Spirit, who Jesus said would “guide you into all truth” (John 16:13).
The problem for truthseekers is evaluating the various teachers or claimants to knowledge, especially when their messages are contradictory. In my opinion humanism provides no hope for ultimate “oughtness”, because there is no logical way to avoid moral relativism without a superhuman Judge. Karmaism offers a rationale for reincarnation, but I have explained why I view it as incredible. Naturalism does not even provide a rationale for morality/the UMI, but rather it implies that what is, is right. However, I do find reasons to believe NT theism is true.
While conducting a comprehensive comparison of theistic religions is not my desire, I think any open-minded truthseeker who compares the NT teachings of Jesus and Paul with the founding scriptures of other religions will reach the same conclusion as I have:
The NT is the most credible canon or collection of writings purporting to be a communique from God. The NT hope for heaven is based on evidence in support of Jesus’ claim to be Messiah/Christ, which includes: the prophecy or foreshadowing of His life (in various OT scriptures, including Isa. 53 and Psa. 22, and by the sacrificial system), the purpose of His death (as explained in the NT, such as Heb. 7:18-10:18), and the probability or credibility of His resurrection (in history as recorded by the last chapters of the Gospels and Rom. 1:3-4).
