InSpiritIn Truth,
Truly you do not understand what being made a new creation in Christ means if you think that we who are born of God still retain the old man of sin nature in the first Adam.
Again, you show your misunderstanding of the fall and why Christ came and what He accomplished. Christ renewed the nature of all men. He gave life to all men, to the world. Christ did not save you as an individual, but as part of His whole creation embodied in our physical natures. We became mortal because of Adam's sin. God permitted Satan to have dominion over this world through death. Which is why scripture is so clear on what Christ accomplished by His death and resurrection. It was to defeat Satan and His works. I can assure you that you do not have that new nature in this life. We will all become immortal at the resurrection. That will be the consumation or His resurrection and all death shall end.
The nature you seem to be referencing is the new relationship with Christ which was made possible by Christ's accomplishment. Having a relationship with man is why we were created. Christ renewed creation by restoring life, and an eternal existence again.
Those who are not born again of the Spirit still retain the old nature of sin, and are flesh, carnally minded and are still dead in their sins and trespasses.
Hardly. you are conflating two different aspects of our salvation and its purpose to restore the possibility of a relationship, not only in this life, but for an eternity.
They are deceived by the power of Satan because they have believed the lie and are of his spirit because they have rejected the Truth about Jesus Christ.
Many believers have fallen and many more will fall before He comes. In fact, scripture is quite clear that many will lose faith in those last days. As long as you can breathe you can be decieved. There is no guarantee that you cannot be deceived.
2 Corinthians 5:17
Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
This is referencing the perfect human being. One that has not only been given life, but has also chosen to enter into a relationship with Christ and to be transformed into the Likeness of Christ.
Your explanations still exhibit a total disconnect from the fall and why Christ came in the first place. You seem to think that Christ came to save you as an individual, rather than make it possible for you as an individual to freely choose to enter into a relationship.
