God has made it plain that Solomon was searching things out:You're making the same mistake Catholics make: calling into question that which God has made plain. Solomon is as clear about what happens when we die as is the nose on your face.
“And I gave my heart to seek and search out by wisdom concerning all things that are done under heaven” (Ecc 1:13)
“I explored with my mind how to stimulate my body with wine while my mind was guiding me wisely, and how to take hold of folly,
until I could see what good there is for the sons of men to do under heaven the few years of their lives.” (Ecc 2:3)
“I applied mine heart to know, and to search, and to seek out wisdom, and the reason of things,
and to know the wickedness of folly, even of foolishness and madness:” (Ecc7:25)
This is how Solomon describes his purpose for writing this book.“I explored with my mind how to stimulate my body with wine while my mind was guiding me wisely, and how to take hold of folly,
until I could see what good there is for the sons of men to do under heaven the few years of their lives.” (Ecc 2:3)
“I applied mine heart to know, and to search, and to seek out wisdom, and the reason of things,
and to know the wickedness of folly, even of foolishness and madness:” (Ecc7:25)
By the end of the book, Solomon discovered that to live for things "under the sun" alone is vanity. Therefore he concluded that God ought to be feared. Solomon explored many things...some true and some untrue. His wisdom guided him through his journey of exploration, reminding him of reality outside the paradigm he was exploring (Ecc 2:3, 2:9, 3:17), which he found to be meaningless...because it is a false paradigm."without regard for eternal consequences"??? Is that why he concludes his book by saying we must fear and obey God and prepare for the eternal consequences of the Judgment?
Why do you characterize as "rejectable" that which Solomon himself says he sought out as "acceptable words" in his book?
As a KJV onlyist, you would probably be unwilling to discuss that. But to keep the peace, I will say this: the Hebrew says Solomon "sought" certain things. It does not say he found them.
I didn't lump all of these together. However, the things I did list share a common denominator: they are the logical outworking of someone who doesn't consider the afterlife. For example, "the earth abides forever". It's simply untrue. God will destroy the earth and make a new one, untainted by sin (2 Pet 3:10, 13, Rev 21:27).Why lump that in with self evident truths such as there's nothing in Sheol, life apart from God is meaningless, animals and humans live by the same "Breath of Life" power of God, there's nothing new under the sun, and the meek shall inherit the Earth?
