Does the Old Testament teach enough about resurrection to build real knowledge about it?
No. The Old Testament alludes to resurrection and shows believers expected it, but it does not say enough to build real knowledge. Daniel 12 provides the clearest revelation, while Job and David also made reference to resurrection life. Yet those references still fall short of a full doctrine.
Les explains that Paul lays out resurrection in the later part of 1 Corinthians 15 and in 1 and 2 Thessalonians, where church age believers are caught up to meet the Lord in the air. But the Old Testament believer also needed to be addressed, so Les goes back to Daniel chapter 12. Les teaches that the Old Testament certainly alludes to resurrection, and its believers certainly believed in a resurrection, but not enough is said about it in the Old Testament to build any real knowledge concerning it. Daniel chapter 12 probably says the most of anything, although Job made reference to his resurrection life, and David expected to be resurrected. Daniel 12 lays it out as clearly as any place, beginning with Michael standing up for Israel, a time of trouble such as never was—the tribulation—and Israel being delivered, everyone found written in the book. It also shows that unbelievers are not resurrected at the same time as believers.
