I can only surmise that we acquire a greater understanding and love and so maybe we're "in love" with everyone! For that matter, will the concept of "male" and "female" exist in Heaven? I presume that procreation doesn't exist and that it is replaced by something far greater. I guess I am unable to conceptualize what it is that awaits us. Of course, I totally trust God and know it will be indescribably great!
