It is important to pray in preparation for a sermon. Father has mentioned that sermon leaders should prepare for as much as three hours, exercising the utmost sincerity before attempting to give a one-hour sermon or lecture. Write an outline of the sermon. Read the Bible, the Principle, or True Father's speeches to add references, parables, and testimonies. Before giving a sermon, I spend more time praying for family members than for the sermon.
True sermons are words from a life that has been full of blood, sweat and tears.
Delivery of the Message. Sermon leaders must be cautious not to give judgmental sermons which would be difficult for either members or guests to receive. When the message is strong, the person presenting the sermon should be aware of the effect his or her words might have upon the listeners, and keep the delivery as positive and light as possible. It is important to remember also that a sermon is given not simply to entertain the audience. It is to share God's way, the path of the Principle, and the tradition of the True Parents.
