We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life.
Romans 6:4
In the Bible, people are baptized at the first available opportunity after they have repented of their sin and placed their faith in Christ. Baptism which takes place before a person has placed their faith in Christ is not true baptism according to the Bible.
