They like to walk around in flowing robes and love to be greeted in the marketplaces and have the most important seats in the synagogues and the places of honor at banquets. They devour widows' houses and for a show make lengthy prayers. Such men will be punished most severely. In this passage of scripture, we see the Sadducees, who have wrongly interpreted some of the writings of Moses and then used their misinterpretation to support and prove their own viewpoint - that there is no resurrection of the dead. We also meet the teachers of the law.
Human beings have no righteousness of our own.
We need to let God be God. Our part is simply to obey. If we accept God s instruction in obedience, we will be changed into the likeness of Christ and His righteousness will be credited to us. The last paragraph of this scripture is a sober warning from our Lord not to follow the example of the teachers of the law who put on a fake show before men of their piety and obedience to God while before God, their hearts and lives were full of evil. Such men will be punished most severely.
