In 2021, Randy Alcorn was interviewed on the topic of Heaven at the C.S. Lewis Conference. In this clip, he talks about present Heaven and the New Earth and if people in present Heaven can see what going on on earth.

In the following video clip, Randy Alcorn talks about what houses might be like in Heaven. He also talks about time in Heaven and how humans are finite creatures, but God is infinite.
