They believe in numerous resurrections, each one being for a particular group of people, and in an eternal earthly paradise as a literal fulfilment of Isaiah 65:21: "''They shall build houses and inhabit them; They shall plant vineyards and eat their fruit''" [earthly resurrection for the good (the "remnants" or the "other sheep"), with the exception of 144,000 (the "little flock") who would go to "Heaven"].
They do not believe in the immortality of the soul (sharing this belief as well as that of the earthly paradise with Seventh Day Adventists). Instead, they believe in the annihilation of the wicked (including, according to their beliefs, the annihilation of both Satan and Adam, the first man), i.e., they do not believe in the eternal punishment of sinners. They also do not believe in the intercession of the departed saints.
Jehovah's Witnesses predicted that Jesus would come in 1914 to judge the Earth and annihilate the wicked. When nothing supernatural happened in 1914, they changed the year to 1925 then many times thereafter.
