Vooke you are foaming in the mouth again. Jonah's prophecy was about the end-time for Nineveh (if they did not repent). Ellen G. White's prophecies were also conditional.
"It was not the will of God that the coming of Christ should be thus delayed. God did not design that His people, Israel, should wander forty years in the wilderness. He promised to lead them directly to the land of Canaan, and establish them there a holy, healthy, people. But those to whom it was first preached, went not in 'because of unbelief.' Their hearts were filled with murmuring, rebellion, and hatred, and He could not fulfill His covenant with them.
"For forty years did unbelief, murmuring, and rebellion shut out ancient Israel from the land of Canaan. The same sins have delayed the entrance of modern Israel into the heavenly Canaan. In neither case were the promises of God at fault. It is the unbelief, the worldliness, unconsecration, and strife among the Lord's professed people that have kept us in this world of sin and sorrow so many years."--MS. 4, 1883. (Quoted in Evangelism, pp. 695, 696.)
Are you saying Ellen G. White was a "stupid prick" because she prophesied like Jonah did, or because she also linked cancer with tobacco smoking and infected meat (both facts of which which modern science confirms)?
