Answer:
"The energy, the faith, the devotion which we bring to this endeavor will light our country and all who serve it-and the glow from that fire can truly light the world."
Step-by-step explanation:
With this quote, Kenedy tried to say that all the hard work and unity of the people of the U.S., as well as the world, will pay off.
The fire and light that would endeavor the country, in his words, is a metaphor for the goodness and freedom that will spread if people support it and fight for it.
Fire is the common metaphor for energy and unity (just like the flame on the Statue of Liberty is the symbol of friendship of France and the US), while the light is the symbol of wellness, good times and freedom.
