Ephesians 4:25 Therefore each of you must put off falsehood and speak truthfully to your neighbour, for we are all members of one body.
Living in close proximity to lots of people tends to give you a different look on life to living out in the country.
When you are one of very few people you tend to try and get on with everyone to make life a bit easier to live. But living with many people bring out distrust and all manner of other bad sides!
God wants us to be able to live with hope and love and in communion with the people close to us; that means putting aside lies and distrust and living like our lives depend on each other.
God wants that sort of close relationship with us even more!
