To love her. Christ is head of the church because He won us over by His love. A man is the head of his home by loving his wife. Being the head means being the leader. The man leads by giving love.
Love involves commitment and care.
When you love a person you will act it and say it . Many man forget to remind their wives verbally that they love them. Even Jesus took the time to remind us again and again, with the hundreds of promises in His word, about how much He loves us and cares for us. Being the head of the home does not mean bringing home the biggest pay packet or reminding your wife that she must submit to you. Being the head is recognising that you are the giver.
