‘And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.’ – Revelation 11:15
The seventh trumpet is the final judgement to come upon the earth. Christ sets up His kingdom, and rewards his faithful people. They receive a home in Heaven, a crown of life and live with Jesus forever.
All who have chosen to reject the kingdom of Christ, and those who have persecuted the saints, will receive their final reward as well. God will leave them to crumble to dust in the lake of fire intended for Satan and his angels.
