Evangelicalism is a branch of Christianity that emphasizes the authority of the Bible, personal faith in Jesus Christ, and the importance of sharing the Christian message with others. Evangelicals often focus on a personal relationship with God and the need for spiritual rebirth, which is sometimes referred to as being "born again." This movement has its roots in the 18th and 19th centuries, influenced by the Great Awakening and other revivalist movements. Evangelicalism is diverse, encompassing various denominations and beliefs, but it generally prioritizes evangelism, social justice, and a commitment to spreading the Christian faith.
