"Attend to your family" is a difficult subject...it probably doesn't matter what I say, someone is going to be offended.
"Husbands love your wives...wives obey your husband" (Colossians 3:18-19) I probably just offended half the population, oh well...I didn't make the rules, God did.
Attending to your family simply means take responsibility for your role as husband or wife (if you're single, this section may not apply, so cut me some slack).
A ship can only have one Captain...the husband is the head of the family (assuming he's still around) Men, it's your job to provide and protect. You may think that abdicating that role to your wife makes you "progressive; trust me, being a "Stay-at-home" Dad while your wife works is not noble. It may be man's way, but it's not God's way.
Wives, you are to submit yourself to your own husband. Yeah, good luck getting that message through to the #metoo crowd. Although the "church" (and society in general) kow-tow to women, the role-reversal prevalent today is a major contributor to most of our problems and why there are so many single moms struggling to raise a family on their own. The Bible says a woman "uncovered" (not submitting to her husband) is like a divorced woman...and predictably, most of them are divorced.
After fifty years of marriage I can tell you, getting your house in order today will be one of the most difficult things you do, but a house out of order is filled with chaos, strife and contempt. It's like a house built on sand, when the floods come, it will wash away.
If you want a happier, healthier, wealthier life: Attend to your family.
