Some like to talk about the attributes of our soul thinking they understand it, when they really do not.
Our soul is immortal until... or IF... God destroys it. That's different than claiming the soul is not immortal, isn't it?
In case you didn't know, per Lord Jesus' promise of John 11:26, that means the soul of those who believe on Him is 'deemed' immortal already. And if you don't believe that, then why did you believe on Christ's Blood shed upon His cross so that you might have eternal life through Him?
John 11:26
26 And whosoever liveth and believeth in Me shall never die. Believest thou this?
KJV
Once again, many claim things about the 'soul' which God created as part of our makeup, but rarely do they consult all the facts of Bible Scripture about it. They certainly will never understand about the 'soul' from using the things of this material world to discern it. Yet that is often what they attempt.
Our 'soul' part is attached with our 'spirit' part, and is of heavenly substance, because it originates from that other dimension called the heavenly. Our soul/spirit can be separated from our flesh body, as written. And because the terms 'soul' and 'spirit' are often used interchangeably, it simply is meant because they both are always together and refer to the person.
