I really agree with these lines but in real world another things happen, even with confidence. Just because life has its own mysteries.
There are people with much faith or confidente or hope that die in banal accidents ou suffer a lot with diseases, hunger, opression . There are people with no faith that prevail, leave a life of confort and abundancy.
I think the most important thing is live and pause to see, listen, fell the life. And decide what to do.
