We are all like street-lamp lighters. In the old days, there was a person in every town who would light the street-lamps with a light he carried at the end of a long pole.
On the street-corners, the lamps were there in readiness, waiting to be lit; sometimes, however, the lamps are not as easily accessible. There are lamps in forsaken places, in deserts, or at sea. There must be someone to light even those lamps, so that they may fulfill their purpose and light up the paths of others.
It is written, "The soul of man is the candle of G‑d." We must make it our mission to light up the souls of others with the light of Torah and Mitzvot.
Sometimes it is easier, they are close, nearby; sometimes they are in a desert, or at sea. There must be someone who will reach out to light those lamps.
