The PST position as related on the BB inevitably resorts to the "wrath of God" being poured out at the crucifixion, and some manner of God abandoning - deserting, turning His back, - on the Son.
But as to why I posted that from the "IFCA" is to show that even those who embrace the "Doctrines of Grace" can and do hold to Christ died for all men, irregardless. That the blood was for all humanity, irregardless.
That redemption is by the grace of God in the gift (endowment) of faith (belief) specifically to those whom the Father has chosen as He purposes.
It is unfortunate that many have chased after what is in error:
The view of some that the blood is sufficient / efficient is not found in Scriptures.
The view of some that the blood was shed only for a few of the many is not found in Scriptures.
The view that the blood shed brings automatic salvation to a few or to many is not found in Scriptures.
Salvation is in one word - belief.
Blood was shed for all that forgiveness is for all, BUT that does not mean that all are saved!
Those that believe are saved, those that do not believe are condemned.
