While I believe the Orthodox church echoes your emphasis on God's majesty and foreknowledge, I am confused by things such as the parable of the "Unsaveable son"( what the Greek translates to instead of prodigal).
As well as other indications that God welcomes those who come at the 11th hour, such as the Paschal sermon of John Chrysostom.
It is difficult to reconcile these kinds of things with a God who would choose some to be damned without any chance at all. Doesn't God also have perfect mercy and love, and how can this be reconciled with the idea of elected as saved?
