"Si lees la historia descubrirás que los cristianos que más hicieron por el mundo actual fueron precisamente aquellos que más pensaron en el próximo."
— C. S. Lewis
Simplified Meaning:
People who made the biggest positive impact on our world often did so because they believed in a better future life after this one. They had strong beliefs about heaven or a better existence after death, and this influenced their actions here on Earth. For example, many early hospitals and schools were founded by Christians who wanted to help others, because they felt it was their duty to be kind and helpful in this life to achieve a good life in the next. It's like if a person knows they will receive a reward for good deeds, they might be more motivated to act kindly and helpfully. These people’s belief in an afterlife made them work harder to make this world better for everyone. So, thinking about a better future can inspire us to do good and improve our current world.
