In 2016, One Light Church was planted out of Southlands Church in Brea, California USA in partnership with the Advance Movement of churches.

After taking vision trips to Myanmar and Thailand in 2013, 2014, and 2015, Southlands sensed a call from God to plant a Gospel-centered, Spirit-empowered church in Chiang Rai, Thailand. The vision was to begin by gathering English-speakers, including expats, missionaries, and English-speaking local people with the hope of growing into a multiplying church that gathers, disciples, and raises up local, indigenous leaders to both lead the church and be sent out to evangelize and plant more New Testament churches in the region and beyond.

As the sending churches, Southlands a d the Advance Movement of churches continue to support One Light Church through leadership, finances, prayer, and encouragement.
