The missionary organization operates ministries in India, Myanmar (Burma), Cambodia and in Thailand, where it maintains its Asia offices. Worldwide Faith Missions was founded by Maas in 1972, following a world tour for the Wesleyan Missionary Council, for which he was the president. He was invited to speak at a large a convention in southern India attended by 20,000 people. It was in a primitive area near the Bay of Bengal, where there were many starving children, homeless widows, and sacrificial pastors and evangelists laboring under great difficulties with little support. It was there that the Lord spoke to Dr. Maas that he was to care for these suffering people. God promised that if he would feed, clothe, house and educate the homeless children, that the Lord would save them, call them into His service, and use them to minister to their own villages. He pledged to sponsor 25 homeless children, to be cared for under the supervision of a respected pastor.
From this humble beginning, the outgrowth has been the establishment of over 25 orphanages, many of whom are supported and operated by various American missionary organizations. Thousands of children have been reared in the Homes. Many are now pastors and missionaries to their own people, and scores are respected citizens contributing to the progress of their villages and their country.
Literally hundreds of Churches have been founded as an outgrowth of this humble beginning, as Worldwide Faith Missions continues to plant new Churches in the neediest rural areas.
During his recent tour, Maas visited several towns in Isan (northeast Thailand), including Chiang Mai, Chiang Rai, and Nakhon Phanom, the place where Ho Chi Minh lived for 7 years during the 1920s and site of the Ho Chi Minh Clock Tower. He conducted a prayer service in the historic St Anna Christian Church. The church is located on the banks of the Mekong River. Materials for the church, built in 1925, were carried overland from Hanoi, Vietnam, and by boat over the Mekong River.
Maas also ministered to the Karen "Longneck" tribes who live in a small village near the Golden Triangle, where Thailand, Burma, and Laos meet. The island in the Mekong River is considered "no man's land”, and was once where the drug lords conducted the opium trade. Maas also visited a small village in Laos, which is a future site for a new mission ministry.
