There exists among many
Evangelical Protestants a dogma
based on some passages in the
Bible called millennialism
which means a "thousand
year reign." The basis for
millennialism is found in the
Book of Revelation.
Revelation 20:1-15
Then I saw an angel come down from heaven, holding
in his hand the key to the abyss and a heavy chain.
He seized the dragon, the ancient serpent, which is
the Devil or Satan, and tied it up for a thousand years
and threw it into the abyss, which he locked over it and
sealed, so that it could no longer lead the nations astray
until the thousand years are completed. After this, it is
to be released for a short time.
