I heard this from somebody. This is not a doctrine that he is pushing, but this is his theory. Romans 8:30 says the following: He believes that God is able to regenerate His elect people independent of gospel preaching, thus, according to him, God is able to issue the call to His elect thru the Spirit as well, the same way that the Spirit preached the gospel to Abraham. What think ye ? Again, let me reiterate, this is not doctrine, but, something he personally believes and shared with me.
