The tale of Robertson and the smugglers gives us an insight as to the reason for our effort of praying for a good year on Rosh Hashanah and Yom Kippur.
Rosh Hashanah is similar to a coronation day. On this day, we accept G-d's sovereignty over every aspect of our lives. We mark the act of acknowledging G-d's sovereignty with the blast of the shofar (ram's horn).
