My wife and I have attended two grandparenting summits, one last year and another recently, both in the Dallas, TX area. We are excited about starting a GP chapter in our church! The leaders of this event have stressed the need for intentional GP in our churches and communities to build upon existing relationships with our grandchildren and children. Last year there were about 800 people in attendance in Frisco, TX. This year there were about 1,000 people in Rockwall, TX. In the US there are some 30M Christian GP out of approximately 78M.
In a culture that has been changing rapidly due to technology, social media, and changing social values, the Bible has some clear things to say (in the OT and NT) about the family. See, e.g. Deut. 4:9. Read more about this new movement by visiting The Legacy Coalition website below.
