"‘If we had lived in the days of our ancestors, we would not have joined them in shedding the prophets’ blood.’ Thus you bear witness against yourselves." Why does Jesus say this? Because someone who says, "I will not sin" or "I will never betray you Lord," is a liar, is not being honest with himself, not really humble about our sinfulness. This fundamental dishonest hypocrisy is the foundation of murdering prophets, hidden pride and self-righteousness. From all these evils, deliver us. Forgive us whitewashed sepulchers and blind guides. Make us humble as you are humble and faithful as you are faithful.
