Randy Alcorn and Sean McDowell speak in depth about Heaven, and discuss the questions: Is it fun? Will we know everything? Will there be marriage? They also address other common questions people ask about Heaven and the New Earth.  

When we receive our glorified bodies and relocate to the New Earth, it will culminate history, not erase it. And nothing will negate or minimize the fact that we were members of families here on Earth. 

Jesus said the institution of human marriage would end, having fulfilled its purpose. But He never hinted that deep relationships between married people would end.
