You keep passing judgements with the labels "regenerated" and "unregenerated", while I despise this kind of black and white thinking. In the parable of the sowere, there are FOUR kinds of soils representing four kinds of spiritual conditions. The first one, the stony ground, immediately rejects the seed of the gospel; the fourth one, the fertile ground, swallows it and slowly nurture it, it may take a long time for the seed to grow its root before it sprouts.
But what about the other two? The shallow ground and the thorny ground? According to a glass-half-empty conclusion, those are fake Christians, they're never saved and never will be; according to a glass-half-full conclusion, though, those are the vast majority of the mission field, shallow ground can be tilled, thorny ground can be weeded, their conditions are not permanent. Here it seems like you're the one with a glass-half-empty conclusion, I'm the one with a glass-half-full conclusion.
