How much do you cherish the body? What plans do you make that don’t involved the body? If you watch your mind, you’ll know how much you cherish the body, even as you go about your daily activities. Those little flare ups in emotion signal that you’ve chosen attack.
Not only is attack not of God, but if you look close enough, you might find attack is everything that is not Supreme Happiness, without exception! Even boredom is a form of attack, as is competition. These are misuses of the body. The only right use of the body is the purpose the Holy Spirit is asking you to use: the acceptance for the correction of error.
