22 Wives, submit to your own husbands, as to the Lord. 23 For the husband is the head of the wife even as Christ is the head of the church, his body, and is himself its Saviour. 24 Now as the church submits to Christ, so also wives should submit in everything to their husbands.
In order to follow Christ, believers must become somewhat feminine. We respond to Christ as a wife responds to her husband - in obedient submission. There is no room in the church for alpha male types. Christ fulfils this role. He is our alpha.
And he delights to choose people (male and female) who delight in being beta. Compare Jesus' encounters with Nicodemus (Jn 3) and with the Samaritan woman (Jn 4). Jesus was not pleased with Nicodemus' masculine competitiveness and took him down a peg or ten. He favoured the more feminine response of the Samaritan woman.
God gave Christianity a feminine feel on purpose. Throughout history his choice has consistently been for the underdog - quiet, bookish Jacob over big hairy Esau , harp playing poet David over beefy Goliath, the village of Bethlehem over the city of Jerusalem, a stable over a palace... and now, the oppressed gender over the oppressor gender. It makes sense that Christianity has a distinctly feminine feel. If one wants to be part of God's kingdom he/she will need to leave macho behind and learn to submit to Christ as a woman does to her husband.
Of course to speak of Christianity having a feminine feel is silly. I want to stay in the complementarian camp, but Mr. Piper, you are making it really hard.
