Let us not kid ourselves. Today's gospel only reinforces our conviction about the fact that we can be led astray by deceitful people. Adam and Eve's experience with the serpent continues nowadays. Satan is always on the prowl looking for fresh victims. Hence, our dear Lord Jesus Christ asks us to beware of false prophets. These latter can come nowadays to our homes and bedrooms because of TV, movies, etc and the pervasive Internet. Satan continues to hunt for victims to deceive and lead away from the truth and moral goodness. Jesus reveals a method to detect this before it harms us. Check their fruits, their products, their graduates, their later lives, etc. If the results show fruits that are not good, then we should be wary of the danger present in such teachers, or prophets.
