The very process of salvation is miraculous and the spiritual knows that where the natural man cannot believe that it is even possible let alone believe that it could happen to him. But he that is spiritual judgeth all things, yet he himself is judged of no man. But we have the mind of Christ. When you believe the Word of God and obey it, you become a new creature. Once you have had that experience you will understand it.
Old things pass away, all things become new.
You are a new creature. You that have never become new creatures do not understand this. Maybe you believe that you cannot become a new creature. Maybe you believe that your case is too hard for God. Maybe you believe that you are different and therefore God cannot make a new creature out of you.
