Good leaders manage expectations. Good leaders provide clarity and a path forward to eliminate surprise and disappointment.  Since the beginning, the Lord makes it clear that all will be well for those who do His will.  

As Jesus concludes the Sermon on the Mount in Matthew's Gospel, he reiterates His Father's expectation.  The crowds who follow Him are impressed with His prophesies, healings, and mighty works, yet they are nevertheless filled with false expectations about entering the Kingdom. Jesus addresses their self-deception, "Not every one who says to me, 'Lord,Lord,' shall enter the kingdom of heaven, but he who dos the will of my Father who is in heaven." So why are the crowds astonished at his teaching?
