What Paul says here often presents great difficulties under modern conditions, especially when young people must choose between caring for parents and furthering their ambitions or establishing a home. Paul teaches that not only children but also grandchildren have a definite obligation to live their religion by providing for their needy parents or grandparents. He bluntly states that they are to repay them for all their kindness and sacrifices. A child can never wholly repay this debt, but still he should consider it a sacred obligation to make it up as much as possible.
