Luke 20:27-47 Marriage in heaven?

Luke 20:27-40 Marriage in the resurrection. (Matt 22:23-33, Mark 12:18-27). The Sadducees were a peculiar sect that apparently supported the Jewish priesthood and were fellow-travelers with the Pharisees, but taught that there is no resurrection. So they attempted to trap Jesus into admitting that His teaching of the resurrection would force people into morally ambiguous situations. That is, God required a man to marry his brother's widow to raise up children in his name (Deut 25:5-10), but if all are resurrected, how could she avoid polygamy? Doesn't this make resurrection absurd? Jesus' answer is straightforward - that they didn't have a clue about the spiritual reality of resurrection. As we see in the case of Jesus' resurrection, His glorified body was not subject to normal human limitations. Now we might cut a bit of slack to the Sadducees, because there had previously been a few resurrections (not clear if this was before or after Lazarus was raised, but Jesus had raised a number of children from the dead), and after those resurrections, it would appear that the person who had come back from the dead was normal.

          But Jesus' answer is nonetheless instructive. In the resurrection there is no marriage, but the resurrected are like the angels of God. We don't know exactly what this means, but it appears that the transcendent relationship directly with God in the glorified post-resurrection body provides that consummation of a relationship that marriage is only a picture of. Marriage and sexuality are used repeatedly in both Old and New Testaments as a picture of the relationship between Christ and the believer, or God and Israel, or Christ and the church. This includes the Song of Solomon, the book of Hosea, Jesus' parables about marriage, Paul's explanation of marriage in Ephesians 5, and the description of the New Jerusalem in Rev 21:2.

Luke 20:41-44 Jesus poses a question to the Sadducees by quoting Psalm 110:1. The point of this question is that even in the Old Testament, there are hints about how spiritual realities cannot be explained by natural logic. Why would David call his son, or future descendant, Lord? Of course, we know that David was looking forward to that day when the very Son of God would be incarnate in the flesh that was descended from David. But by rejecting supernatural intervention in nature, the Sadducees could not answer Jesus' question.

Luke 20:45-47 Jesus' warning to His disciples about the scribes seems almost superfluous at this point. Perhaps this is just a recap of the situation with Jesus adding that He had seriously engaged the Sadducees because, even though they rejected spiritual things, they were seriously asking questions and genuinely trying to understand God, while the scribes were simply using God as a means to feather their own nest. Perhaps a closeout to an extended visit to the temple that had started in Luke 19 when He had driven the money changers out.
