What happens to marriage on the New Earth I think I can safely say that humans were designed not to operate as a single solitary person but as part of a unit of two -- both as referenced by Gen 3:16-17 (see mentions of husband and wife in said passages) and ingrained feelings that appear to be a part of every person I know of (near as I can tell anyway...). However, there also seems to be support for there being no marriage after we are resurrected in Matthew 22:30. Can someone clear up my confusion on this topic?
Putting the verse you just cited (Matthew 22:30) back into context will clear up a bit of your confusion. First of all, the question was posed by the Jewish leaders about tedious Jewish customs in an attempt to catch Jesus off guard, as they frequently tried to do. The chapter even goes as far as to specify that they were Sadducees, which did not even believe in the resurrection. Furthermore, Christ's answer that they will not be married nor given in marriage refers to this contrived example (if you look at the KJV translation, it says "they" rather than "people") and not to couples in general. So this verse does not provide much support against marriage after the resurrection.

My experience is that most Christians agree that marriage between husband and wife is ordained by God...at least for this mortal life. The Bible does not say much else about marriage after death, and there doesn't seem to be a consensus among the various denominations as to the state of marriage after death.
