@SpecterAndBride Romans 5:2: "We have access by faith into this grace."
Grace is available, but it is accessed by faith.
No faith, no access - not universal salvation.
@grcastleberry Think about it this way: if non-Calvinists are right, does salvation cease to belong to God?
If the answer is no, then your argument collapses.
And if the answer is yes, then you have far bigger problems.
