When I read that Paul recommended living single, I took him at his word, and determined to remain single. In the end, I changed my mind, and found myself remaining single for about 12 years! I didn't like it, and I don't understand Paul in the way I once did! ;)Theological discussions for another thread some day.
Btw, I do wonder about shows of affection in eternity. The mansion and the house by the sea and all that quite honestly won't mean much to me without a companion. Maybe we all treat each other like companions, since scripture states we will know even as we are known, but I wanna live with someone. I don't wanna live alone in Heaven. I think it will still hold true that it is not good for a man to be alone.
So I understand being alone, and having to travel distances to have quality friends--they aren't super-abundant! But you have to accept the ones God gives you--they turn out to be special.
I do agree that without companionship life is meaningless. Jesus isn't going to spread himself out across billions of people at one time! ;) So I think the enjoyment of fellowship will be much greater, and some kind of spiritual intimacy will be much greater.
I don't think we're allowed to know too much, or we'd all commit suicide on the spot! Just kidding....
