The cantatas for the Sunday after New Year include BWV 153 and BWV 58.
BWV 153 can be heard here.
BWV 153 is divided into three parts, each of which in turn includes a Chorale, Aria, and Recitative, but in a different order for each of the three parts. The concluding Chorale includes three verses of a hymn that would have been known by the congregation.
BWV 58 recordings are available here.
The concluding Soprano/bass aria/chorale is memorable.
