Ukuze uqhubeke upheqe ngenkathi ulalele, dlala umsindo ewindini elisha.

To defile means to make something impure or dirty. To be made impure, it has to be pure, and to be made dirty, it has to be clean. In Matthew, Jesus emphasizes the things that defile us and explains from where they come. This teaching indirectly answers one of the most troubling questions: How did evil come into being in a good world created by a loving God?
