"14 To understand how Jehovah’s Witnesses have fulfilled Jesus’ prophecy with regard to the scope of the preaching work, let us consider some facts. There are approximately 600,000 members of the clergy in the various denominations in the United States, where there are some 1,200,000 Witnesses of Jehovah. Worldwide, the Roman Catholic Church has a little over 400,000 priests. Now consider the number of Witnesses involved in the Bible-based Kingdom-preaching work. Worldwide, some eight million volunteer ministers preach to people in 240 lands. What an amazing work is being accomplished, all to Jehovah’s praise and glory!—Ps. 34:1; 51:15."
