A divinely inspired, relevant message
If you are listening to a sermon, you will receive some good advice from a friend. You will be wise to follow it.
If you are delivering a sermon, you will be accused of double-crossing someone.
(See Preacher; Pulpit)
If you dreamed of hearing a sermon, or if you delivered one yourself in the dream, you need to learn an important personal lesson. You may be harboring feelings of guilt and self-punishment. You need to quit being so hard on yourself.
Someone is trying to give one advice, which should be listened to.
