About
LIGHT is a supporting ministry of the Seventh-day Adventist Church, operated by a group of lay members who are passionate about sharing the gospel with every people group. The ministry exists to train church members in practical health evangelism that multiplies disciples globally by using Christ’s method of loving service.
History
LIGHT began with a desire to see more members of the church actively sharing the wonderful message of health and salvation.
With the understanding that many will work if they are only taught how to begin, we knew the greatest need was to make short training courses available to everyone. In 2005 two experimental training programs were field-tested in a Western European and a Central Asian country to see what would result. The success of these programs encouraged us to organize LIGHT to better facilitate the global expansion of medical missionary work. Through the help of various ministry leaders in Outpost Centers International, ASI, and Wildwood Lifestyle Center, LIGHT was developed.
In 2008 ASI, under the General Conference of the Seventh-day Adventist Church, accepted LIGHT as an official member organization. Since that time LIGHT has trained tens of thousands of people in more than 100 countries.
