During our lifetime, we encounter some truly miserable and harsh individuals. These are the people that do nothing but complain, criticize, and shake their finger at you. They don't have a shred of happiness in their lives; if you see them smile, it's probably because they've come up with a witty line to use against you. Sometimes these people even claim that they know Jesus. When I have to deal with these types of people, I have to keep reminding myself that God loves them too. They have a lot of chains to break before they reach the joy that's available regardless of the circumstances dealt. My first thought is to get away from them as quickly as possible, but that's not always possible. My best advice is to pray through every step. As long as they are not a physical threat, you can look at the situation from a kingdom prospective and worry about the outcome as it presents itself.
For everyone who does wicked things hates the light and does not come to the light, lest his works should be exposed. John 3:20
A soft answer turns away wrath, but a harsh word stirs up anger. Proverbs 15:1
