Over 2,500 Jehovah's Witnesses members gathered for their annual convention in Flatbush this weekend.

The theme of the 2018 convention is courage, whether that be in relationships, difficult decisions and in the Bible.

Organizers say as traditional religions worldwide have faced dwindling numbers, Jehovah's Witnesses have attracted around 3,000 new members per year in the U.S.

Organizer Henry Wilson says he thinks the growing numbers are thanks to the group's focus on applying the bible to their own lives.

The convention is a free event where topics ranging from marriage, elderly care and being a student of the Bible will be covered.
