Mac Hammond graduated from Virginia Military Institute in 1965 with a Bachelor's degree in English. Upon graduation, he entered the Air Force with a regular officer's commission and reported for pilot training at Moody Air Force Base in Georgia. He received his wings in November 1966, and subsequently served two tours of duty in Southeast Asia, accumulating 198 combat missions. He was honorably discharged in 1970 with the rank of Captain. Between 1970 and 1980, Mac was involved in varying capacities in the general aviation industry including ownership of a successful air cargo business serving the Midwestern United States. A business merger brought the Hammonds to Minneapolis where they ultimately founded Living Word Christian Center in 1980 with 12 people in attendance.
After nearly 25 years, that group of twelve people has grown into an active church body of more than 9,000 members. Today some of the outreaches that spring from Living Word include Maranatha Christian Academy, a fully-accredited, pre-K through 12th grade Christian school; Maranatha College, an evening and weekend college with an uncompromising Christian environment; Living Free Recovery Services, a state licensed outpatient treatment facility for chemical dependency; Club 3 Degrees, a cutting-edge Christian music club which is smoke/alcohol free; The Compassion Center, a multi-faceted outreach to inner-city residents; CFAITH, an online cooperative missionary outreach of hundreds of national and international organizations providing faith-based content and a nonprofit family oriented ISP; and a national and international media outreach that includes hundreds of audio/video teaching series, the Winner's Way broadcast, Prayer Notes publication, and Winner's Way magazine.
