Jesus Christ was simply a good son, good brother, and a hard worker for His first 30 years of life. He only spent His last three years preaching.
In order to be a good CHRISTian, we ought to focus on being a good son/daughter before anything else.
Ok...but didn't Jesus supposedly say, "If you come to me but will not leave your family, you cannot be my follower. You must love me more than your father, mother, wife, children, brothers, and sisters—even more than your own life!" So if I were a Christian that personally didn't want to "be a good son/daughter before anything else" and instead abandon my parents, I could just ignore your interpretation and assure myself that the Bible says the opposite.
And that's how Christianity works. Whatever your personality subjectively inclines you to value, you can interpret the Bible consistently with that worldview. Hence the 40,000+ distinct denominations.
So yeah, I think we should all have happy healthy family relationships in an ideal world, but I don't think Christianity particularly helps with that. You can interpret it that way if you want, or not. A central message of the Bible seems to be that perfect love is based on unquestionable authority and fear of violent punishment, and I do think that's objectively a terrible way to run a family but unfortunately we see a lot of Christians running their families on this model.
