[3][4] Thompson grew up in Oak Lawn, Illinois where he was raised a Roman Catholic and worked for United Parcel Service for the majority of his early adulthood.

[1][5] He moved to Homer Township, Illinois, where he sought "practical answers to life's problems and a real personal relationship with Jesus Christ", and began considering other denominations.

Family Harvest Church, which can hold over 3,000 congregants in one service,[4] has been called a megachurch, noted for its theater chairs, projection screens, polished singing performances, stage lighting, amplified sound, and TV and web shows.

[13] In 1986, in an effort to promote that Halloween is "historically evil" and harmful to children, Thompson's church scheduled a "Hallelujah Party" in its place on October 31.

[14] In 2005, Family Harvest Church opposed Tinley Park's decision to zone an off-track betting facility, as destructive of local ideals.
