And as they went, they entered a village of the Samaritans, to prepare for Him.  But they did not receive Him, because His face was set for the journey to Jerusalem.  And when His disciples James and John saw this, they said, "Lord, do You want us to command fire to come down from heaven and consume them, just as Elijah did?" 

But He turned and rebuked them, and said, "You do not know what manner of spirit you are of.  For the Son of Man did not come to destroy men's lives but to save them." 

Luke 9:52-56   (NKJV)
