Therefore, if you have any home movies, I earnestly advise you to burn them and to be baptized to get born again. (7.12)
Jack is just full of advice. Look at all the transformations he mentions here. Burning home movies is a metaphorical attempt to change the past. Baptism and being "born again" represents religious transformation.

Jack is talking about the tears he shed upon learning that he is the sole beneficiary in the Judge's will. This is probably the only time we see Jack break down and cry. His heart has begun to thaw along with the deep freeze of his past.
