How does one distinguish between providence and bad luck?
It is not always obvious when one should trust and do nothing to correct their difficult circuмstances and when one should fight to repair the damage or replace the loss.
If the fingers on your mouse hand get shattered broken in a freak vending machine accident is that God telling you to stay off the internet or just a weird accident?
If you cannot get a job or hold down a job, is that Providence telling you that God does not want you working at all, or working in the field you were in, or God, life, reality, suggesting that you need to learn to hold down a job and perhaps change your attitudes or ways of dealing with people around you?
Angels appearing to people and speaking to them make it clear what the will of God was. In life, however, we don't typically hear voices from Heaven.
