Deep down we all want to be able to trust each other's character and not be tricked, fooled, or played. But it is hard to trust because regularly people do not keep it real. This was an issue with the Pharisees that Jesus addresses in Matthew 5 (as part of the Sermon on the Mount). They had the tendency to make vows with loopholes so they could not be pinned down. Jesus directly challenges them on what it means to have integrity. And it is a message to us all on how to respond and keep our word to one another.
