As my brothers and sisters have said, we have never made a prophesy about the end of the world.
We have interpreted Bible prophesies incorrectly, There is nothing wrong with that.
We do not believe the world will be destroyed. We believe that the governments will be overthrown by Jesus and he will rid the earth of those who refuse to worship his God and Father, Jehovah.
The Trinitarian religions believe that Jesus will rapture all his people to heaven, come to the earth and give the people left behind a tribulation beyond all tribulations and then destroy the earth sending everybody to hell to be tortured forever.
The trinitarians believe in the end of the world, not Jehovah's Witnesses.
