The gist of Elder Andersen's message to the audience of around 1,200 was that each person should strive to live Christ-like lives and to exemplify the Savior at all times. Stake President Nelson was suitably impressed:
“Elder Andersen is a special witness of Jesus Christ. Having him here was a rare privilege. Each person who heard him teach and bear testimony of Christ was strengthened and edified, and is now likely resolved to live a more Christ-like life, which will, I think, bless all of Brooklyn and Staten Island.”
LDS Church News provides a summary of the history of the Church in New York State. The Brooklyn New York Stake is a relatively young stake, not organized as an entity until 1998. It's a part of the Manhattan New York Temple District; stake members perform their temple ordinances at the Manhattan Temple on 125 Columbus Avenue near the Lincoln Center.
