You wouldn’t. It’s the unanimous testimony of Church Fathers, and of the Scriptures themselves, about a faithful remnant (and Christ’s saying, “When the Son of man cometh again, will he find faith in the world?”) that the vast majority of souls do go to Hell, and even a majority of professing Christian souls go to Hell. When St Augustine was preaching to a group of Christians, he said that he doubted one in ten were elect (although he may have been hyperbolizing).
Think of this. There are more people alive at this moment than have died in the entire history of humankind. This is true whether one accepts the ancient earth evolutionist calculations, or whether one accepts the Biblical creation-fall-redemption calculations.
There are about 2 billions of Christians (counting all denomionations, even the quais-Christian ones) and 7 billions of people currently alive in the world. Even if every single person who ever claimed to be a Christian currently living was saved, over 72% of the world’s population is lost. Hinduism, Mohammedanism, Buddhism, Atheism, Evolutionism and the like, are not salvific religions.
Now, do you believe that every professed Christian is saved and amongst the elect? Pentecostals, Lutherans, Romans, Orthodox, Presbyterians, and even Mormons and Jehovah’s Witnesses? Of course not.
Do you believe that every Catholic is saved and amongst the elect? Catholics are about 1 billion of persons, or half the world’s Christian population. If all Catholics and half of the Orthodox and Protestants are saved, over 80% of the world’s population is lost.
Do you believe the Protestants which deny the Incarnation, Trinity, Resurrection, and Atonement are saved? Of course not. Take an additional two percent off. If one takes Augustine’s testimony, only 200m Christians are amongst the elect, and none other, leaving thirty-four out of every thirty-five souls currently living lost.
I could continue multiplying examples, but, suffice it to say, it seems unlikely in the highest that more than one-half of the professed Christians are amongst the elect, at the absolute uttermost limit. (It is more likely to be smaller, based on the consistent Patristic and Scriptural testimony.)
This places an upper limit, according to human reason, that about one in seven persons (14%) currently living will be saved. In pure numerical terms, “Satan ‘won’”, but God created everything, both seen and unseen; he created numbers, and souls, and Satan. Can numbers have a victory over the God who gives them meaning?
