Meaning: The quote you have provided reflects the core belief of the Seventh-day Adventist Church, a Christian denomination that emerged in the mid-19th century. The church's belief in its divine commission to prepare the world for the Second Coming of Jesus Christ is central to its identity and mission.

The Seventh-day Adventist Church was officially established in 1863 and has since grown into a global denomination with millions of members. The church's beliefs are based on the teachings of the Bible, and it holds the Second Coming of Jesus Christ as a central tenet of its faith. The belief that they have been chosen by God to prepare the world for this event is deeply rooted in their theological framework.

Seventh-day Adventists believe that they have a unique role in fulfilling the biblical prophecy of the Second Coming of Christ. They see themselves as part of the remnant church, a faithful group of believers chosen by God to proclaim the three angels' messages of Revelation 14:6-12 to the world. These messages call people to worship the Creator, announce the fall of Babylon, and warn against receiving the mark of the beast. This mission of spreading the gospel and preparing people for the Second Coming is at the core of the Seventh-day Adventist identity.

The belief in being chosen by God for a specific mission is not unique to the Seventh-day Adventist Church. Many religious traditions have similar beliefs about their role in God's plan for humanity. However, for Seventh-day Adventists, this belief translates into a strong emphasis on evangelism, education, and health initiatives aimed at fulfilling their mission. The church operates a vast network of schools, hospitals, and humanitarian organizations around the world, all in service of its mission to prepare the world for the Second Coming.

The Seventh-day Adventist Church's emphasis on healthy living and longevity is closely tied to its belief in preparing for the Second Coming of Christ. They believe that caring for one's body is essential for being spiritually and physically prepared for the events preceding the Second Coming. As a result, the church promotes a vegetarian diet, abstinence from harmful substances, and regular exercise as part of its holistic approach to health and wellness.

The belief in being chosen by God to prepare the world for the Second Coming also influences the way Seventh-day Adventists approach their relationships with others. They are called to be messengers of hope and bearers of good news, which often leads them to engage in community service and outreach programs. The church's emphasis on social responsibility and compassion is a direct result of its belief in the imminent return of Jesus Christ.
