We all struggle with our emotions..Many believers undeniably struggle with the idea of a just God having an innocent infant die from a natural disaster or suffer from an incurable disease.
..but we have to come to terms with the injustices in this life.
The idea that there is "no god" does not change reality in the slightest.
The believer knows that this life is as "a blink of an eye" .. it is not our permanent abode.
