Sheep who become lost need salvation.
In our day and time, only those who are not born again need "salvation".
In our day and time, those who are born again do not need to be born again over and over and over.
Again, do you even know what it means to be born again?
Please explain how a soul dies, or perishes.
Justification, saved by grace, born again, regenerated, Reconciled to God are references to the same thing.
Instead of arguing that what we have in our day and time does not far surpass that which was revealed prior to Day of Pentecost, that which God hid in Himself, His eternal purpose in Christ Jesus:
Ephesians 3:
9 And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:
10 To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God,
11 According to the eternal purpose which he purposed in Christ Jesus our Lord:
12 In whom we have boldness and access with confidence by the faith of him.
Just accept by faith that which is freely given to the born again believer in Christ Jesus our Lord. Jesus Christ died to bring us close to Father. Why do you hide this truth under a bushel?
