Generally I would say that HN is not the place for religious discussions, but in this particular case, it seems quite appropos and the comment was very respectfully phrased.

If the op is dissatisfied with his life, then perhaps changing his career or living circumstances as most other comments talk aobut is the way to fix that. But perhaps looking at religion is. Christianity is only one possible religion to explore, but I think it has helped me be a better person personally and sheats is just sharing his experience with it. Sheats phrased it quite respectfully and as one option to consider, not trying to push it as something the OP must do.
