Some parents these days have no time to devote to their children, let alone monitor their TV and gaming habits. The term "Personal Responsibility" seems to have very little meaning to some parents these days because they are too involved in their own lives getting material wealth, rather than paying attention to their kids and paying attention to the responsibilities that God has entrusted them with... their kids and their proper upbringing.
Please review
1 Timothy 5:7 (NLT):
8 "But those who won't care for their own relatives, especially those living in the same household, have denied what we believe. Such people are worse than unbelievers."
