How Does A Physical Body Help Protect Us Against Evil?

Here are some very interesting quotes from Joseph Smith:

“Before the foundation of Earth in the Grand Counsel… the Spirits of all Men were subject to oppression & the express purpose of God in Givening [them] a tabernacle was to arm [them] against the power of Darkness.”

“For it is a Natureal thing with those spirits that has the most power to bore down on those of lesser power.”

Words of Joseph Smith, 62, 68

This is a fascinating doctrine, and powerful. We often think (because it is true) that our bodies are fallen and are the primary reason we are vulnerable to sin. But this teaching gives insight into how we can overcome sin and evil. How do we use our bodies to overcome the Adversary?

One possible answer: Through the sanctification of our bodies to our spirit - which is the submission of the flesh to the spirit - brings tremendous power and strength over the powers of darkness. How does this relate to the resurrection? What are your thoughts?
