Death is the punishment God promised on all who sin. We have all sinned, and will all experience death. But what about the soul? Will our souls experience the 'second death'? [Revelation 20:6]
If we repent and receive the baptism of Jesus Christ, then we receive of His 'resurrection life', and our souls are made alive. At His coming, the faithful will receive a new spiritual body and they will be drawn to Christ.
1 Thessalonians 4:16-17.
I wouldn't rely on the testimony of the false prophet Paul for your "salvation". Those who are "saved"/"survive" during the day of the LORD (Joel 2:31-32) are those on Mount Zion and in Jerusalem. The "day of the LORD" happens at the beginnning of the millennium, not the end. If you haven't entered into "life" (Matthew 19:17) before death, don't expect to have anything to do with the "first resurrection" which is constituted by those who heed the testimony of Yeshua and keep the Commandments of God (Revelation 14:12) The "second death" addressed by Rev 20:6, refers to those not in the first resurrection, which happens 1000 years after the first resurrection. The second death is after the white throne judgment, regarding those not in the book of life, who are thrown into the lake of fire (Revelation 20:15). Those who escape the "second death" are those who "overcome" (Revelation 2:11). As for the "soul", it is a combination of dust and the breath of life from God. When you die, the breath of life returns to God, and is without a body, and cannot hear or speak.
