Bear good fruits.
In today's Gospel, Jesus gives us a criteria of discerning and differentiating the good and the bad disciples, the true and false prophets. As Jésus disciples we must only bear good fruits through our daily actions. True followers will indeed avoid false prophets, false teachings, wrong doing, evil deeds, immorality, drug, lies, greed, materialism, gluttony and any other sin.
Good disciples are reputed to have a good heart.
Lord mold our heart, and refashion them so that we may bear good fruits. Amen.
