Do you feel ashamed of your bodily functions? Do you know that you don’t need to? We are created in God’s image. That means we are every bit as generative and instinctive as God is. We have survival coded into our genes. That is how God intended it.
He gave us those emotions corresponding to our bodily functions, not to be ashamed of, but to give us the equipment so he can ask us to go forth and multiply, to fill the Earth and subdue it.
To subdue the earth we need our necessary instinctive phenomena. Survival instinct, biological imperatives to multiply, and the emotions that help us to nurture and support our offspring are all built in.
There is no shame in that. We are wonderfully made. Please be happy that you can fulfill God’s promises to the next generation.
