Prayer, meditation and spirituality at the UN are fascinating subjects. All major world religions are accredited to the United Nations as non-governmental organizations. For example, no less than twenty-four Catholic organizations are represented at the UN. Several of the world's religious leaders have visited the international organization. Most memorable were the visits of His Holiness Pope Paul VI during the General Assembly in 1965 and of Pope John Paul II in 1979. Many religions have special invocations, prayers, hymns and services for the United Nations. The most important examples are those of the Catholic, the Unitarian-Universalist, the Baptist and the Bahai faiths.
In the paragraphs before they use this quote it is made quite clear that it is being used to show that being an NGO of the UN means rejecting God's Kingdom:
9 Today, Jehovah's Witnesses warn that a flood of executional armies will soon sweep over Christendom. Moreover, they point to the true place of refuge from that flood. They quote Isaiah 28:16, which says: "This is what the Sovereign Lord Jehovah has said: 'Here I am laying as a foundation in Zion a stone, a tried stone, the precious corner of a sure foundation. No one exercising faith will get panicky.'" Who is this 'precious cornerstone'? The apostle Peter quoted these words and applied them to Jesus Christ. (1 Peter 2:6) If Christendom had sought peace with Jehovah's King, Jesus Christ, then she would have avoided the coming flash flood.-Compare Luke 19:42-44.
10 However, she has not done so. Instead, in her quest for peace and security, she insinuates herself into the favor of the political leaders of the nations-this despite the Bible's warning that friendship with the world is enmity with God. (James 4:4) Moreover, in 1919 she strongly advocated the League of Nations as man's best hope for peace. Since 1945 she has put her hope in the United Nations. (Compare Revelation 17:3, 11.) How extensive is her involvement with this organization?
