i am not going to give chapter and verse. you can look it up on your own . see if you can follow this:
#1) faith comes by hearing , and hearing by the word of God
#2) without faith it is impossible to please God.
#3) when a person’ s ways please the Lord He(God) makes even his enemies to be at prace with him.
#4) Jesus said,” he who has an ear , let him hear.

Listening to the word of God and his counsel is a weapon.
