Eschatology is the study of the end times or final events in human history, often focusing on themes of judgment, resurrection, and the ultimate fate of humanity. It is a significant concept in various religious traditions, including Christianity, Islam, and Judaism, each offering unique perspectives on what will happen at the end of the world. In Christianity, eschatology includes beliefs about the second coming of Jesus Christ, the final judgment, and the establishment of a new heaven and earth. Similarly, in Islam, eschatological beliefs involve the Day of Judgment, where individuals are held accountable for their actions, leading to eternal reward or punishment.
