again, there's a difference between seeing everything happening on earth, and hearing your name when you are called.

the Bible doesn't specify whether they can hear you. But it does specify that there are deeper truths to be learned than are made clear in the Bible. Those who do it right can be led deeper into the mysteries.

so again, if you really want to know an answer that isn't contained in the Bible, you're best bet is to ask God in prayer. The answer will come.
