That response also does not say anything

. It's a bunch of politically correct statements that anyone could write. It would waste less paper to just say, "OGK."
It says quite a lot.
1.No one will be lost that can be saved- God is sovereign and the divine will, will obtain.
2. The limits to salvation, whatever they may be, are known only to God- It is not for us to decide who or how many are saved, and certainly not for us to declare some are damned as if the limits of God's mercy are known to us.
3. God is a holy God who is not to be trifled with- We shouldn't be presumptuous as if salvation is a trite thing.
4. No one will be saved except by grace alone- self explanatory
5. And no judge could possibly be more gracious than our Lord and Savior, Jesus Christ. Therein lies hope that the just judge is merciful.
Does it say all will be saved? No, but it leaves open the possibility. More importantly, it doesn't declare that many will be damned eternally as those who support ECT insist on.
That statement captures the inherit ambiguity of the scriptures regarding this question and the revealed mercy of God. I think it's a step in the right direction and away from the long history of presuming many will be damned forever.
I have no idea what is supposed to be politically correct about it, unless you think discussions about salvation are inherently political.
