I think at a general level, male headship involves sacrificial love and service. God made men with bodies that they can wear out working. So working hard to provide for your family, working hard to pursue the hearts of your kids and wife, working hard to avoid entangling sin.
It involves praying for and with his wife, praying for and with his kids, and modeling the gospel and reminding them of its truths. So when he sins against his wife or his kids, modeling the gospel by confessing that to them, apologizing, and asking them for forgiveness. It means putting his wife and her needs first. Knowing her strengths and building her up in them, and knowing how she feels most loved and served and doing those things for her.
It means being a one-woman man and making his wife his standard of beauty.
It means laying himself down for his wife, and training his kids in righteousness.
These things can look a little different depending on the couple, so that's just a general idea of the kind of husband and father I hope to be.
These videos explain and describe well what I'm saying, and a lot of my idea of what a good husband and father should be comes from listening to Matt Chandler's sermons (hence my username). Apparently you can only post one video per post, so please don't hate me, but I'm going to post a few as I feel that they are helpful and pertinent.
