This document discusses why missions are important based on two main reasons from the Bible. First, because we should love God and want to spread his fame and glory among all nations as commanded. Second, because we should love our neighbors and want to rescue the lost near and far by bringing them the gospel, as all people are sinful and separated from God without it. It concludes that the Great Commandment to love God and love our neighbors fuels engaging in missions to both spread God's fame and save the lost.
