This document provides an introduction and overview of supernatural visions experienced by orphans at the Adullam Rescue Mission in China founded by H.A. Baker and his wife. It discusses how the orphans, who came from impoverished backgrounds, began receiving visions of heaven, angels, and revelations from God after an outpouring of the Holy Spirit. The introduction questions why such supernatural experiences described in the Bible are not seen more commonly today and argues they cannot be explained naturalistically but were genuine visitations from God.
