Sadly, a couple of family members ...
I know what you mean. I also have unsaved family members. They are welcome to whatever I leave behind at the rapture.
I saw a thread a few weeks ago, about the spiritual body we will receive, being a real super hero type body, that would make superman jealous. Of course, the reason for all the power God will give us in our spiritual body, is to give Him glory, but I think He will give us extraordinary powers, to accomplish His will.
Maranatha bro.
