The Knowledge of Salvation
Some Evangelical Protestant and Pentecostal Christians believe
that an individual Christian can have a certain unmistakable
knowledge, an assurance from God, that one is saved.
Catholic Christians believe that a Christian can have a firm
hope and confidence of salvation, but that no one can know
of one's final salvation with absolute certainly. This fact is
amply affirmed in the New Testament.
... but whoever
endures to the end
But the one who
perseveres to the end
will be saved.
