Mat 22:30 For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven.

Christ refers to the afterlife as "the rising up," we assume, of the dead. He says here that the risen do not marry. He describes them as like the "angels of God in heaven." "Heaven" is from ouranos, which means "sky," "the universe." Of course, when God's messagers visit earth, they take on human form, but is it their form or lack of it that Chrit is referring to here?

In terms of Christ's three realms, marriage is that of relationships. In the afterlife, relationships with other people change. Our primary relationship or partnership is with God. This is why Christ compares the risen to the "angels of God" because we will be defined by our relationship with God and not each other. Though God, we will know others intimately, but we will know all others infinitely. Since God is everywhere, in everyone, how could such a relationship be exclusive?

"Resurrection" is from anastasis, which means , "a standing up," "removal," "a rising up," "a setting up," and "rising from a seat." It is the noun form of anistêmi, which means "to make stand up," "to raise," "to wake up," "to build up," "to restore," "to rouse to action," "to stir up," and "to make people rise."

"Angels" is from angelos, which means "messenger" and "envoys" though it became to mean "semi-divine beings" in later use.
