I believe that it most ties to belief in Yeshua, Yahweh. Those that believe in Him will have strong family values. The less exposure to, and belief in, or acknowledgement of the possibility of the existence of the God of the Bible, the less likely to unconditionally love a child, to the point of sacrificing one’s life for that child.
The good news is that there are Bible-believing, and more importantly, a number of Bible-FOLLOWING people spread in pockets, all over the Western world, though those numbers may be declining. Unfortunately, there are plenty of Laodecian Christians trying to live with one foot in the Kingdom and one foot in the World. It cannot be done. In Matthew 12:30, Jesus states, “Anyone who isn’t with me opposes me, and anyone who isn’t working with me is actually working against me.”
As belief in the God of the Bible wanes in the West, the belief in ‘self as god’ grows, since such people have accountability to no one but themselves. A lay pastor friend of mine was telling me about negotiations for a lot for his mobile home. When he tried to speak of Jesus to the owner of the land, a Jewish man, the man referred to himself as his own god, that Abraham never existed and that both the OT and NT were nothing but stories. He was his own god and he worshipped money. My friend has asked me to pray for this man. I have, and continue to do so.
What about the vestige of Roman culture that we came from? It’s not doing very well, either. We should all study more to find out why.
