"Show me the people with whom you keep regular company, and that will tell me a lot about your character."
Bishop John Gimenez
Fellowship with other believers is very important. We must also guard against close fellowship with those of poor character and loose tongues - this can have a very negative affect upon us. We should have some boundaries up regarding our fellowship and be cautious with whom we associate.
Jesus was a friend of sinners and talked to everyone, I can hear someone saying! Jesus also only shared his personal life with 12 and was closer to 3 then the others.
