I agree. On the 'thoughts' bit, i meant that, i think our 'Mentality' in Heaven will be radically different because, it seems like our lives in Heaven will be more GOD-Centered than they are here on Earth where our lives and responsibilities (Work, School, Family and even SIN) get in the way of constant communion with him. It seems like there is always some obstacle keeping us from perfect constant union with our GOD.
Also, remember when the Sadducees tried to challenge Jesus on this very issue regarding our lives in Heaven; Speaking in
(MATTHEW 22 : 23-30) on whether the institution of marriage will be recognized in Heaven after we enter our final rest, HE gave them a reply that implied that, though the lady in question may have been someone's Wife (she was Married to 7 different men) while she was on Earth, in Heaven she is just one of the Saints - Pure and Perfect like the Angels of GOD are, NOT someone's Wife !!
Marriage or Coupling (or Intimacy

) on Earth serves a definite purpose, whether it be Companionship or Child-Bearing or even Fun - but from my understanding, in Heaven, GOD satisfies all our needs - Our final PERFECT COMMUNION with HIM for all Eternity will be enough for us.
As an example: i'm assuming that Apostle Paul who was unmarried while on Earth, isn't online on CC in Heaven trawling the Singles Forum telling himself that GOD has a plan for his life - GOD IS HIS LIFE, his EVERYTHING !!
