Jesus said to preach the gospel to every creature in the Great Commission, not just His people my friend. You are anti-means, anti-missionary, anti-Great Commission. It is sad the view you hold to, as it is anti-biblical and yet you mock those who hazard their lives in getting the gospel to those living in remote places.
The cross did not save all of God's elect at the very moment Jesus died upon the cross my friend. We were lost, born dead in Adam, and our salvation, which is eternal by the way, was accomplished in time, via the preaching of the gospel. Saying they regenerate needs to hear the gospel to be saved is preposterous. If someone is saved, they are regenerate, if they are regenerate, they are saved. You saying that people are saved and then later are saved by the gospel is a ludicrous statement to make. God saves people via the gospel of Jesus Christ.
