Only the just, the righteous, will rise at Christ's second coming. God will raise the martyred saints to eternal life, but the unjust dead will not be resurrected until the end of this period. If we have the Holy Spirit dwelling in us when we die, we will be resurrected through the power of that same Spirit at that time. In addition to the dead in Christ, those who are true Christians at His coming will rise in the first resurrection. The Feast of Trumpets celebrates the second coming of Jesus Christ to intervene in world affairs, resurrect the first fruits, and establish God's Kingdom on earth.
