Emotional Men & Rational Women

Here's something I recently read in Jim and Sarah Sumner's book, Just How Married Do You Want to Be? (IVP, 2008):

Christians have to be careful not to buy into the paradigms of the world. It's the world that says that men, being masculine, are rational and women, being feminine, are emotional. The Bible doesn't say that at all. It flies in the face of Scripture to say that men are not emotional- because that would make them incapable of rejoicing in the Lord or mimicking Christ's anger or grieving about sin with the Holy Spirit. It likewise flies in the face of Scripture to say that women are not rational- because that would make them incapable of following the commandments to renew their minds and meditate on Scripture and take every thought captive to Christ. According to the Bible, men and women alike are created in the image of God (Genesis 1:26-27); thus both are emotional and rational.
