Wouldn't be fair to say that those who do not preach are being disobediant to God? And if "Plan B." is other Calvinists preaching, I have no problem with "Plan B."
Absolutely. Not only "fair," but correct.
And if "Plan B." is other Calvinists preaching, I have no problem with "Plan B."
BUT, do you believe that if no Calvinists (or anyone for that matter) preached the gospel, [and we fully recognize the case, but what if it was?] that the "elect" would still come to God?
