Our souls are immortal, there is no way to destroy a soul once it has been created.
Then Matt 10 is a bluff?
Mt 10:28"And do not fear those who kill the body but cannot kill the soul. But rather fear Him who is able to destroy both soul and body in hell.
To say that this means this means God is "able" but never does is an assumption and goes against what the normal reading of that verse would indicate.
Secondly the soul does die:
Eze 18:4"Behold, all souls are Mine; The soul of the father As well as the soul of the son is Mine; The soul who sins shall die.
Eze 18:20"The soul who sins shall die. The son shall not bear the guilt of the father, nor the father bear the guilt of the son. The righteousness of the righteous shall be upon himself, and the wickedness of the wicked shall be upon himself.
God can do anything, but He clearly says He will not destroy our soul.
Where is this clearly taught in scripture?
We are not immortal because of us, but only because He has made us immortal.
Where is this found in scripture? If we are made mortal then why did Christ bring immortality?
2ti 1:10but has now been revealed by the appearing of our Savior Jesus Christ, who has abolished death and brought life and immortality to light through the gospel,
This is confusing to me because to seek immortality implies that we may not find it. If I am right that immortality means existing forever without end then all will find it without seeking.
Then you are wrong in one of these positions. Scripture seems to teach only those in Christ gain immortality.
Adam was the only man to whom immortality was an accurate characteristic. He lost that when he sinned.
Prove that from scripture.
There will never be an end to our existance, not that God could not end it, but he will not.
Joh 3:16 "For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
What does “perish” mean? Perish seems to indicate the opposite of everlasting life.
Here is one definition Thayer gives for “perish”:
apollumi
Thayer Definition:
1) to destroy
1a) to put out of the way entirely, abolish, put an end to ruin
This seems to allow for annihilationism.
What was provided by the Tree of Life?
Ge 3:22 Then the Lord God said, "Behold, the man has become like one of Us, to know good and evil. And now, lest he put out his hand and take also of the tree of life, and eat,
and live forever"
If Adam already had immortality, if Adam was already created to live forever then why remove him from access to a tree that provides something he already has?
Perhaps had he eaten of the tree he would have gained immortality but God in his grace removed that tree so that Adam would not exist forever in a fallen state.
