It’s not surprising that some Arminians now espouse postmortem salvation. If you begin with an Arminian premise, then there’s an inexorable logic to that next move.
In the traditional Arminian view, this life is your only opportunity to be saved. Once you die, that’s a lost opportunity.
Yet it’s perfectly obvious that, in this life, every human being doesn’t have the same opportunity to believe the Gospel. Opportunities to believe the Gospel are quite inequitable.
Many people never have a chance to even hear the Gospel. On the other hand, some people hear the Gospel at one time or another, but come from a background which is highly prejudicial to the Gospel. They grew up in a very legalistic church. Or they were brainwashed by secular humanism. Or they were indoctrinated in Islam. And so on and so forth.
So even if they happen to hear the Gospel, they don’t hear it with the same pair of ears as someone who was raised in loving Christian home. It’s hard to overcome a well-entrenched bias. And even if you can, you’re operating at a handicap. Others don’t suffer from your handicap.
Likewise, some people attend an evangelical church with fine expository preaching. Others attend a church in which they don’t know enough to know what they’re missing. It’s a vicious circle. The preaching which they’re used to hearing is so deficient that they have no standard of comparison.
In addition, some people have lots of leisure time to study Christian literature. Other people have to work two or three jobs to make ends meet.
So, if you define a “fair chance” the way Arminians define it, then it’s absurd to suppose that everyone has a fair chance in this life to believe the Gospel. The range of impediments and disparities is stark. Hence, the Arminian deadline is a very arbitrary deadline–given the egalitarian assumptions which underwrite the Arminian position.
As such, extending the “grace period” into the afterlife is a necessary equalizer–necessary given the Arminian premise. It tries to level out the vast spiritual inequities in the here-and-now.
And, of course, it’s a short step from postmortem salvation to universal salvation. Everyone will be saved sooner or later–whether in this life or the life to come.
The only equally logical alternative is Calvinism. For Calvinism never predicated salvation on equal freedom of opportunity. Calvinism never took the position that God would be unjust to deny someone a “chance” to be saved.
