According to John Piper,

‘At the heart of mature masculinity is a sense of benevolent responsibility to lead, provide for, and protect women in ways appropriate to a man’s differing relationships.’

and,

‘At the heart of mature femininity is a freeing disposition to affirm, receive, and nurture strength and leadership from worthy men in ways appropriate to a woman’s differing relationships.’

It is not difficult to find fault with these definitions.  The most obvious complaint would be that they focus too much on the single issue of leadership.  Mindful of this, some teachers at Capitol Hill Baptist Church have offered these adaptations:

‘The essence of biblical masculinity is a sense of benevolent responsibility to tend God’s creation, provide for and protect others, and express loving, sacrificial leadership in particular contexts prescribed by God’s Word.’

and,

‘Biblical femininity is displayed in a gracious disposition to cultivate life; to help others flourish; and to affirm, receive, and nurture strength and leadership from worthy men in particular contexts prescribed by God’s Word.’
