Is Your Mouth Cleaned?

In today's Gospel Jesus tells us that nothing that enters in our body make us bad people, but things that go out make us bad people. He was talking about food and its function. I mean people at Jesus's time were arguing about impure food coming into our mouths were the origin of our impurity, but Jesus said what makes us impure it is not the food but it's our feelings and emotions that come from  our hearts that make us sometimes unworthy. This time of the year will be good to us to think if I am carring bad things in our hearts like angry for someone or envy or things that make us sad during the day.
