The Institute in Basic Life Principles (IBLP) is a non-denominational Christian organization that serves as an umbrella organization for several ministries. The IBLP, which has been described as a cult, was established by American Christian minister, Bill Gothard. The stated purpose of the organization is to provide instruction on how to find success in life by following biblical principles. This involves programs that include seminars for ministry, community outreach, troubled youth mentoring, and an international ministry. Children are expected to be home schooled, to always obey their fathers, and adhere strictly to IBLP's interpretations of biblical Scripture. IBLP maintains a post office box in Oak Brook, Illinois (Box One, though the former headquarters building is actually located in nearby Hinsdale, Illinois) as well as a large facility in East Texas near the town of Big Sandy which according to its "Contact Us" site is the organization's headquarters.
