42 Stand then in the Church, stand where I appeared to you, where I am with you. Where the Church is, there is the most solid resting place for your mind, there the support of your soul, where I appeared to you in the bush. You are the bush, I am the fire; the fire in the bush, I in the flesh. Therefore am I the fire, that I may give light to you, that I may consume your thorns, that is, your sins, and show you My grace.
