A guard in charge of a lighthouse along a dangerous coast was given enough oil for one month and told to keep the light burning every night. One day a woman asked for oil so that her children could stay warm. Then a farmer came. His son needed oil for a lamp so he could read. Another needed some for an engine. The guard saw each as a worthy request and gave some oil to satisfy all. By the end of the month, the tank in the lighthouse was dry. That night the beacon was dark and three ships crashed on the rocks. More than one hundred lives were lost. The lighthouse attendant explained what he had done and why. But the prosecutor replied, "You were given only one task: to keep the light burning. Every other thing was secondary. You have no excuse."

Temptation is a choice between good and evil. But perhaps more insidious than temptation is conflict where one must choose between two good options. The lighthouse keeper in our story found himself in such a conflict situation. So also are the would-be disciples in today's gospel story.
