Theological concepts refer to the fundamental ideas and beliefs that shape religious understanding and practice. These concepts often explore the nature of the divine, the purpose of life, and the moral principles that guide human behavior. They can vary significantly across different religions, such as Christianity, Islam, and Hinduism, each offering unique perspectives on spirituality and existence. Key theological concepts include God, salvation, grace, and faith. These ideas help followers make sense of their beliefs and experiences, providing a framework for understanding the world and their place within it. The study of these concepts is essential for both personal faith and interfaith dialogue.
