The mind is that part of a person which gains, stores and processes information. It is by default only affected by the 5 senses.
In the NewBirth we receive a new, perfect spirit. This is SpiritSalvation.
But our mind still holds the same information, opinions and tendencies it did before we were BornAgain.
In order to experience the benefits of AbundantLife our minds must be transformed, renewed so that the MindOfChrist in our NewSpirit takes over our mind.
The Word and the HolySpirit are the ingredients which enable our minds to be transformed. But we must expose our minds to the Word and we must surrender our minds to the HolySpirit in PrayerLanguage for this to happen.
To the extent we do this, our minds are renewed and we experience SoulSalvation.
Our minds will never be completely transformed in this life. We press toward the mark Phi 3:14. At the return of Christ the corruptible will put on incorruption and our SoulSalvation will be complete 1Co 15:50-54.
