you asked for verses that give assurance, i gave them to you- Christ never loses actual souls that are given to him by the father- if he did, the bible would be a lie-
“[28] I give them eternal life, and they will never perish, and no one will snatch them out of my hand. [29] My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father’s hand.”
Strong assigns “Spirit” to the word psuche- Spirit is not the soul- Spirit is what makes us us- it is out life- Here is the definition from the word:
“The Spirit gives life; the flesh counts for nothing. The words I have spoken to you—they are full of the Spirit and life.”
““Jehovah God formed man from the dust of the ground and breathed into his nostrils the breath of life, and man became a living soul.””
The “Breath of life” Is The Spirit that is given by God- the Hebrew Word is Neshamah Meaning “Spirit”
[[pre-supposing that you get to call yourself eternally saved forever. It’s not in the Bible]]
It is in the bible- botrh as direct proclamations, and infered as in the explanation about Christ never losing any of His flock- IF it is possible for a saved person to lose hteir salvaiton, and die immediately and wind up in hell- then the bible is a lie- God specifically proclaimed that NONE of those He gives to Christ will be lost-
[[DOES THIS sound like absolute guarantee of Salvation from John?]]
That verse is not about salvation but remaining in a close relationship with God- We as Christians can walk away from His love and protection- but we are still saved- just as a son can walk away from their parent’s love and protection and still be their son-
John 15 is not about losing salvation- there are many sermons and articles on this fact- it is simply sayign that if a person walks away from God’s love, and is not bearign fruit as a result- they will not be under His love and protection- it doesn’t mean they lose His love though- God will always love them because they are His- The way to remain “UNDER” His love is to keep His commandments (but again this was to the Jews- Whom he had just told that they must Accept Him as Savior in order to ‘abide in Him’- those that don’t will be burned up because they are unsaved- always were- and had no intenion of beign saved- These unsaved were Jews that who took other gods-
Vs 10 is a condition of descipleship, not salvation- just as a son walking away from family is a condition of departure from the family, but not from the blood line-
