Why do some people lose their faith while others hold onto it?

I’ve seen people who were deeply religious suddenly walk away from their beliefs, while others stay strong even through tough times. What do you think makes the difference? Personal experiences welcome!

It really depends on personal experiences and how people process what they go through. Some face challenges that shake their faith, while others find strength in it. Things like life circumstances, new perspectives, and personal struggles can all play a role in how beliefs evolve over time.
