If I may be allowed to quote the Good Book:

"For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."

When you know that your battle is a spiritual one, you seek out the Spiritual Weapons to combat them.

Any search engine would easily point to those "Spiritual Weapons" if one was so inclined to know/want them.
