Should Old Testament prophecies which have an end-time application be interpreted to mean the True Church of Christ, and not any blood descendants of Abraham or any Middle Eastern Nation?

Is Gehenna (Hell) a temporary destination of the damned? Or is it permanent and eternal?

Undeniable additional scriptural proof that this earth will not be desolate for one thousand years, after Christ translates the righteousness from earth to heaven, as our friend, the Seventh-day Adventists, teach.

Will the dead ever be raised to fight against Christ and His Saints; as Mrs. White claimed?

Do the souls of the righteous who die in this dispensation of grace, remain in their graves until they are resurrected ? Or do they go to heaven immediately after death?

In the list of erroneous doctrines, as compiled by Mrs. White, there is this affront: That the sins of the redeemed hosts were ultimately placed upon Satan.

Mrs. White  claimed that Jesus Christ made a final atonement in the heavenly sanctuary in 1844, for all those who could benefit by his mediation pg. 253, last paragraph, the early writings.

Mrs. White claims that those who are raised from the dead at the first resurrection, would spend 1000 years, initially, with Christ in Heaven, during which time, this earth would be desolate and become the home of Satan and his angels for 1000 years (early writings, pg. 290).

Would GOD the Father contradict Jesus' statement of Mark 13:32, and tell Mrs. White the day and the hour of Jesus' second coming?

Can we believe Mrs. White who claimed on pages 127 and 151 of her book "The Early Writings", that GOD had a struggle to send Jesus to earth, to die for the sins of humanity ? or should we believe John 3:16?
