Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified. (Rom 8:30)
I have heard this passage taught by Calvinists as an unbreakable, golden chain of events that happen for all of God's elect. Consider then the following questions:
Q: Do all of the events of Romans 8:30 (predestination, calling, justification, glorification) happen for all of God's sheep?
A: I have never met a Calvinist who would deny that.
Q: Does the gospel (I Cor 15:3-4) reach all of God's sheep?
A: No. Clearly the gospel never reached Job, else he would not have said "HOW can a man be just with God?" (Job 9:2) Neither did the gospel (I Cor 15:3-4) reach any of the OT saints (Eph 3:5). Moreover, the gospel never reaches the infant dying in infancy, yet the bible's testimony is clear that there are saved infants (II Sam 12:23, I Kgs 14:13, Jer 31:15-17)Given the unavoidable force of that logic, what is the "call" of Romans 8:30? It is none other than immediate, Holy Spirit regeneration. It is the life giving fiat of God whereby he imparts the gift of eternal life to his children. God's gift of eternal life is in no more hampered by the distribution of the gospel message today than it was in the time of Seth, or Job, or any other OT saint from Rahab to Jereboam's infant son. God imparts the gift of eternal life to his children irrespective of anything found in them.
Q: So if "calling" happens for all God's sheep, but the gospel does NOT reach all God's sheep, can the gospel be the call of Romans 8:30?
A: Clearly not.
That's an eye-opener for most.
