Being "immortal" is NOT the same as being "eternal", understand this. There is no contradiction, it is simply a misunderstanding on your part. Humans are eternal beings, open your eyes and understand this simple, obvious truth. Never does a human soul pass into non-existence, and "eternity" follows the great white throne judgment, eternity being something that every human is a part of, Sweet Lord.
Spirit =/= Soul
Human: (Body(Soul(Spirit)Soul)Body)
Beast: (Body(Spirit)Body)
Wrong causality, we have souls and are thus eternal beings. Humans do not pass into non-existence at death. Identity is retained at death, clearly scriptural. The soul of man is what persists, and it will persist eternally --> read Isaiah 14 (the men of Sheol not only realize who they are and those around them, but they know who enter). The Great White Throne Judgment is further evidence to the persistence of man's identity after death.
The reason why salvation exists is -because- men are eternal. Salvation does not exist for the animal kingdom because they do not have an eternal disposition, mankind does.
The whole reason why we ae capable of all this is due to the soul that is inescapably set with an eternal disposition
Absolutely not. The extent of animal "spirituality" is limited to ecclesiastes (the "spirit" of beasts) and the term -"living" beings- from genesis. Anytime you actually read the term "soul" it is consistently and exclusively in relation to a human, never a beast. The Bible speaks nothing of animal souls, simply because there is no such thing.
Whether you want to accept it or not, salvation is not extended to animals because they have no eternal disposition as humans do, and the eternal disposition of humankind is accomplished due to the existence of his soul.
So will the trees, grasshoppers, boulders, rocks, pebbles,...etc. Rocks will not be redeemed nor resurrected. You are erroneously applying the verse here
It is not meant to say we are alike animals in any literal form, but in a theological sense. Again, wrongfully applied
"For man goes to his eternal home while mourners go about in the street. Remember Him before the silver cord is broken and the golden bowl is crushed, the pitcher by the well is shattered and the wheel at the cistern is crushed; then the dust will return to the earth as it was, and the spirit will return to God who gave it.” (Ecc.12)
Pay close attention. The spirit returns to God. Do the souls of all men go to God? No (i.e. Rev 20:15). Does the spirit of all men return to God? Yes. However, this happens only at death. The “spirit” is essenatilly the “breath” of God, which is the life of all living beings. Regardless if it is of a righteous man, wicked man, or beast of the earth, at death this life “returns” to God. The soul of man is something different, unique, and as I have been saying, eternal. The Bible speaks more than enough on the state of man’s soul after death (i.e. Sheol/Gehenna).
