Does all the talk about gender issues have your head spinning?
Well this ought to clear the confusion once and for all...
When God created our first parents, Adam and Eve, He made them one make and two models.
So, akin to the manufacture of automobiles... the make is man (or mankind) and the models are male and female.
It's just like the Bible says...
"So God created MAN in his own image, in the image of God he created him; MALE and FEMALE he created them" (Gen.1:27).
Once we see men and women are just two different models of the same make, there's no need to opt for awkward words like 'humankind.'
Neither is there reason for men to feel any shame in being a man, or women to feel any inferiority in being a woman...
... because they're just two different models from the same manufacturer... made with special features and functions.
And embracing the model God made you to be is an important step in fulfilling the purpose He has for you.
