Adult baptism is a Christian practice where individuals, typically over the age of 18, choose to be baptized after making a personal decision to follow Jesus Christ. This form of baptism often symbolizes a public declaration of faith and commitment to the teachings of Christianity. It is usually performed by immersion in water, signifying the washing away of sins and the beginning of a new life in faith. In many denominations, such as Baptists and Methodists, adult baptism is seen as an important step in the spiritual journey. Unlike infant baptism, which is performed on babies, adult baptism requires a conscious choice and understanding of the faith. This practice emphasizes personal responsibility and the importance of a mature commitment to one's beliefs.
