Resurrection, the first
'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.

"At that time shall Michael stand up, the great prince who stands for the children of your people; and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time your people shall be delivered, everyone who shall be found written in the book.
2
Many of those who sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.
