Second Coming
The Second Coming (sometimes called the Second Advent or the Parousia) is a Christian and Islamic belief regarding the future (or past) return of Jesus Christ after his ascension to heaven about two thousand years ago. The idea is based on messianic prophecies and is part of most Christian eschatologies.
Seventh-day Adventist eschatology
The Second Coming of Jesus Christ marks the beginning of the Millennium, according to Adventist teaching. At the second coming, the righteous dead will be resurrected (the "first resurrection", Revelation 20:5), and both they and the righteous living will be taken to heaven to reign with Christ for 1000 years. The rest of mankind (the wicked, or unrighteous) will be killed at the second coming, leaving the earth devoid of human life.
