Kids watch. The older I get one of the things that shows love the most is how spouses treat each other especially in front of the children. I want my son to see the way to treat a woman in the way my husband treats me. I am not referring to gifts (though that is nice), I am talking about kind words and actions that show love.
The tone of your voice. The words that are spoken. The sacrifice of your time. The things that keep a marriage strong and going even when getting along and growing old is challenging. During Sunday school, a kid gave me this answer while filling out the craft and it almost made me cry. This dad gets it and the child sees it.
Love your wife…lead your family.
