Ted’s ministry has helped churches, communities, small groups and individuals in 49 states and 13 foreign countries host The Bible in 90 Days curriculum. Churches hosting The Bible in 90 Days include: Assembly of God, Baptist, Bible, Catholic, Christian, Church of Christ, Community, Episcopal, Evangelical Free, Lutheran, Mennonite, Methodist, Non-denominational, Pentecostal, Presbyterian, United Methodist, and Vineyard.
