What does the Bible say about baptism for the remission of sins?

In Luke 3, John the Baptist preached a baptism of repentance for the remission of sins, which is understood not as a means to obtain forgiveness but as a sign of a turn towards God. John preached that individuals should repent of their sins and believe in Christ, who was to come. The remission of sins is a result of the 'tender mercy of our God' through Jesus Christ, rather than through any works, including baptism. This is further clarified in Acts 19, where Paul underscores that John's baptism pointed people to believe on Christ.
