1 Peter 1:8-9 English Standard Version
8 Though you have not seen him, you love him. Though you do not now see him, you believe in him and rejoice with joy that is inexpressible and filled with glory, 9 obtaining the outcome of your faith, the salvation of your souls.
This is one of the few verses that directly connects salvation to the saving of our souls.
John 3:16-17 English Standard Version
For God So Loved the World
16 “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. 17 For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him.
The most famous quote about being saved indicates the purpose is eternal life and does not state exactly what we are being saved from or what is being saved.
Is the soul life?
John 6:63 English Standard Version (ESV) It is the Spirit who gives life; the flesh is no help at all. The words that I have spoken to you are spirit and life.
If the spirit is life and the flesh is of no help, and the soul is flesh, mind, will, and emotions, then what is being saved?
1 Corinthians 5:5 English Standard Version (ESV) you are to deliver this man to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord.
It seems by this verse that the flesh is not going to survive death, only the spirit.
Perhaps the confusion about saving the soul is over the issues of our conformance into the image of the Son. Our minds are being changed, our will is being changed, and our emotions are being changed. This is a daily process and when we are resurrected into the incorruptible form for the sake of eternal living, whatever souls we have will have been translated into perfection and no longer in need of being changed.
Until then we are left with the daunting task of conformance, a changing of the mind, will and emotions of the individual.
Thank God He did not leave that task up to us.
