I understand in many Protestant circles their theology is once you believe and accept Jesus as your personal Lord and Saviour you have been saved, you will go straight to heaven under the condition that you do not sin again or otherwise your original confession of Jesus was not genuine.
Most Catholics struggle to remain in the state of grace. You mean to tell me our Protestant brethren have always remained in the state of grace after their confession? None of them have even had an impure thought?
The doctrine of “Once Saved, Always Saved” is a heretical Calvinist thought which relies
on the sin of presumption of Salvation. I don’t know if all Protestants are like that, but in-
deed there are some out there who believe that once you’ve been saved, there’s no way
you could undo your salvation.
Our place before God is in a state of flux, though God knows all things. We can believe
and be in a good state of Grace before God, but then many of us could fall away, thus
be unsaved. It is for those who believe, keep believing, endure to the end, who are the
saved people. One can believe, sin, disbelieve, then at the end of his life believe again,
even in that last moment, and he is justified.
God knows all things, but that doesn’t mean we are fated, as that removes the concept
of Free Will. We CHOOSE, then based on our choices are either saved or not saved.
We fall and rise and fall and rise again, there is no certainty to our salvation, that’s
to presumptuous. All we can do is have Faith.
One thought though: For those who are filled with the Holy Spirit, there’s almost no way
that we could resist God’s love and presence. I, for example, was born/confirmed as a
Catholic, became a Pagan pessimistic towards Christianity, the Abraham Religions,
even towards God himself, favoring the Great Mother Goddess instead, but in only
3-4 years, the Holy Spirit didn’t just draw me back, He YANKED me back into the
Faith, and I was saved again. So in a way, “Once Saved, Always Saved” is kinda
true, but not in the way Calvinists today would present it as.
