World to come

The world to come, age to come, heaven on Earth, and the Kingdom of God are eschatological phrases reflecting the belief that the current world or current age is flawed or cursed and will be replaced in the future by a better world, age, or paradise.

The concept is related to, but differs from, the concepts of heaven or the afterlife in that heaven is another place or state of existence generally seen as above the world, and the afterlife is generally an individual's continued existence after death.^{[citation needed]}
