I think I already answered that in post 30.
And why missionaries, the elect will get there anyway>
Primarily because Jesus commanded us to do so. Seems like a good enough reason to me. ;-)
Spurgeon, that grand old Calvinist, said it best:
God did not put a yellow stripe on the faces of the elect, so we are commanded to preach the gospel to every creature, however only the elect will respond.
Contrary to popular urban legend, Calvin was deeply interested in evangelism and sent missionaries out from Geneva in order to find God's elect. (Sources available on request)
Jesus commanded us to go find the elect. Were there no elect in China for centuries, for instance, because no missionary could get in? And if there were Chinese elect born to be saved, why worry? The only ones to feel sorry for are the billions of human fryers without a chance. It would have been better for them not to have been born.
