This Hebrew word means “wind”, “breath” or “spirit”. This is what God breathed in Adam, in the beginning. He breathed Himself into a body made of dirt, then man became a living soul. Without this Ruwach or Spirit of the living God, Adam would have been an immobile body, forever laying on the ground.
It is the spirit that quickens, the flesh (body) profits nothing. John 6:63
Your body cannot help itself without Ruwach in it. This breath that keeps us alive is who we are really.
My body is useless without the wind of life that dwells in it.
I can only do what I do because of the presence of the spirit in my body. I’m are therefore spirit (Ruwach) because I was created in my Father’s image. My Father God is spirit and this is why I’m spirit as well.
Think about it, as long as a spirit is a man/woman, he or she can breathe, live and move. As soon as the spirit departs, humans cease to live and others have to come and bury their body into the ground.
We are spirit.
