Family Worship

On page 334 in GPTG it is speaking concerning family worship. The issue is the lack of time family's spend worshipping together and spiritually growing as a family. It is so true when it said that family worship has been replaced with small-group activities. Obviously, there is nothing wrong with small groups. There are actually many benefits, but I think there is something damaging with replacing family time in worship with other activities. Our society speaks of "family values" more now than it probably ever has, yet Christians value family worship and spiritual growth less now than ever before. What is wrong with this picture?
