Saints are officially declared as being saints after they die.
However, this doesn’t mean that there aren’t very holy people walking around who might not be i.e:- if they died, they might be a declared saint. Fear is the beginning of Wisdom but fear in this sense is more about looking at God, than sin, in the sense that, in awe of God, people don’t wish to spend an eternity without Him, and sin, is, of course, that very means to Hell. Many Saints suffered interiorly, believing they weren’t going to Heaven, and this is because the lines get thinner, the holier one gets. More becomes apparent. It is also a spiritual truth that the closer you get to God, the more spiritual good and bad is discerned, sometimes felt, even physically as well as spiritually. But the saints suffered these torments by trusting in God at all times. They carried their crosses. A lot of the time, with great joy. And that is why looking at God was important for such people: He helped them carry the burden. The closer people get to God, the more they understand the disastrous pattern and effects of sin. And because they loved God, they hated sin.
