“Then Jesus called to the crowd to come and hear. ‘All of you listen,’ he said, ‘and try to understand. It’s not what goes into your body that defiles you; you are defiled by what comes from your heart'” (Mark 7:14-15 NLT)

Jesus explained that sin begins with an attitude of the heart before it becomes a behavior. Focusing on changing the behavior is unfruitful when only faith in Jesus will change the heart. The human heart is born with an attitude of rebellion against God saying, “My will,” rather than “Your will be done.” This teaching of Jesus also served notice that certain Pharisaical cleanliness laws were human additions to the Mosaic law and therefore not binding. This is an example of the saying that “law begets law.” The Pharisees had not lightened the burden of the people, instead they had added to it.
