What significant feature did Ellen Harmon see in her vision related to the fourth commandment?

Ellen Harmon, who later became known as Ellen G. White, experienced a vision that prominently featured a halo of light associated with the fourth commandment, which emphasizes the Sabbath. This halo is significant as it symbolizes the sanctity and divine authority of the Sabbath day, showcasing God's creative power and calling for rest on the seventh day. The light reflects the glory of God's presence and serves as a visual affirmation of the importance of keeping the Sabbath holy. This experience helped to cement the understanding and observance of the fourth commandment within the Seventh-day Adventist tradition, reinforcing the belief in the Sabbath as a sacred institution.

The other options do not align with her vision of the fourth commandment. For instance, the burning bush is a significant biblical symbol focused on God's call and presence but is not specifically linked to the fourth commandment. A voice from heaven conveys messages of divine importance in various biblical contexts but does not represent the specific aspect of Ellen Harmon’s vision concerning the Sabbath. Similarly, an open book may symbolize knowledge or judgment, but it does not directly relate to the fourth commandment as communicated in her vision.
