Hillsong is the worship music arm of Hillsong Church, founded in Sydney, Australia in 1983, and its live recordings became a global standard for contemporary Christian worship through the 1990s and 2000s. Extended wordless refrains built around 'oh' are a signature of that arena worship style, designed for congregations to sing together. Short lifts like this one later spread on soundboards and in edits, where the sincere worship tone gets reused out of context for comedy, awe and mock revelation moments online.
