So, seeing that he can't (understandably) get himself to believe in God, he should find something else to put his faith in.
A good cause for example. Or something that you might call ones lifes work.
True. But he is trying to do just that. He shouldn't.
I always believe that it is not faith that matters in the end, it is how you live
your life. The reason behind is, some said that human exist before religion. Also,
perhaps there are some people throughout their life who never heard of religion.
If there is God and we are going to be judge by 'religiosity', then it becomes
unfair.
To live without believing in any God, on the other hand, might cause you in
confusion: what do you live for, then? Because if there is no God, then there
is no judgment, no life after death, and so on. Once our life is finish, everything
is over. So why struggle in life? etc.
But to blindly believe in something you can't believe is also lying to yourself.
If I were him (he is a Daoist?), I will believe in whatever I believe is true right
now till I find that it is not right. When my understanding is improving and it is
proven to be not right, then I will continue looking. Meanwhile, I'll try to live
life 'correctly'. Because, if I am a gambler and I have no idea whether there is
life after death or not, it is save if I assume the worst case. But that is just me.
