What is the significance of baptism in relation to understanding faith?

In the instance of the eunuch, baptism follows his profession of faith in Jesus Christ, demonstrating that prior understanding and belief are crucial prerequisites for baptism. Philip's response to the eunuch's inquiry about what hinders him from being baptized is centered on belief: 'If thou believest with all thine heart, thou mayest.' Baptism symbolizes the believer's commitment to Christ and is to be administered only after a credible profession of faith, as illustrated in the Great Commission where Jesus commands that all who believe should be baptized.
