"Then the Lord God formed [that is, created the body of] man from the dust of the ground, and breathed into his nostrils the breath of life; and the man became a living being [an individual complete in body and spirit]." Genesis 2:7 (Amplified)
Of all the creatures God mad, Adam was the only one he breathed on. He didn't breathe a second time on Eve, because we are one, like God is trinity... we are tri-parts spirit, soul, and body. Man and Woman are one, much like the trinity, neither one is more important than the other, rather complementary.
Human life is particularly precious and worth safeguarding because we are God-breathed miracles, the crown of creation.
How incredible it is that we were given God's breath of Heaven, into our lungs.
Ours is a worthy cause, to safeguard life, because God formed us so uniquely and personally. He could have spoken us into existence but instead He chose get down into the dust and breath.
