'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

6316. The majority of the learned, it will surprise you to learn, think on the level of the senses. The reason for this is that they have studied different branches of knowledge solely for the sake of renown. They have studied them so that they may be promoted to important positions and thereby earn material gain, not to the end that they may be made wise; for all branches of knowledge that exist in the world of learning are means that may serve to make a person wise or that may serve to make him insane. Once those learned people have been raised to important positions they live, more than those who are simple, on the level of the senses, and they then think it a sign of simplicity to attribute anything to the Divine instead of attributing it to prudence and natural instinct and all else to chance.
