In today's Gospel reading from Matthew 5, Jesus warns that whoever is angry with his brother will be liable to judgment, whoever says, "You fool," will be liable to fiery Gehenna, etc. Then how can we possibly avoid punishment? Recall that after Jesus said to his disciples, "It is easier for a camel to pass through the eye of a needle than for one who is rich to enter the kingdom of God," they asked him who then can be saved. And Jesus looked to them and said, "For human beings this is impossible, but for God all things are possible." So the Lord's rigorous demand for our perfection above must be balanced by his infinite mercy.
