Since its founding, in 1923, that vision has been realized through evangelizing the lost and establishing local congregations in the United States and abroad, through the nurturing and training of believers into leadership on all levels of Church life, and in cooperation with other members of the Body of Christ at large in the fellowship of the Gospel and the fulfillment of the Biblical mandate to be "light" and "salt" on the earth.

Today, the number of members and adherents in the Foursquare Church worldwide now stands at 3,587,835 worshiping in 29,973 churches and meeting places in 123 countries. At the end of the reporting year, there were 48,271 Foursquare ministers and workers.

The Foursquare Church actively participates in the National Association of Evangelicals, The American Bible Society, Pentecostal/Charismatic Churches of North America, the Pentecostal World Conference, and the Evangelical Fellowship of Missions Agencies. Many of its leaders, pastors and members serve on the executive boards and committees of para-church agencies and endeavors, such as the Lausanne Conference on World Evangelization and the America 2000 Outreach.
