Somebody recently said that you cannot mix Christianity with business, or let your faith interfere with your professional life; because it might offend people.

The 1929 Wall Street crash that preceded the 1930's great depression, and the 2008/9 capital market crisis had similar roots.

Grumbling seems to be a natural habit; most people do it a bit, while some make it their trademark.

James has been encouraging the Christian to be patient; trusting Christ and waiting until His will is done (James 5:7-11). Now he looks for evidence of a quiet heart that is confident of God's mercy and grace. The impatient, untrusting or frustrated person may lash out emotionally or physically when life does not go according to their plan, but more often they lash out with words - swear words. James says that swearing, which takes God's Name in vain or trivialises something sacred, is not right (Exodus 20:7). Jesus said the same in Matthew 5:34-36.
