What does the Bible say about gender?

“So God created man in His own image; in the image of God He created him; male and female He created them.” Genesis 1:27

A man is never to lose his masculinity. A woman is never to give up her femininity. God gave you that femaleness. And God gave the male the maleness. A female might object, “Well, I’m not inferior to a man.” That’s right! You’re not inferior to a man. As a matter of fact, you’re superior to a man . . . at being a woman. And a man is superior to a woman at being a man. God made them different that He might make them one. Any society that blurs the distinction between male and female is headed for disintegration and disaster. And in America today, we are reaping the results of disregarding these God-given differences. God made them in the beginning male and female. We honor Him by honoring the way He made us.
