Another necessity when teaching the Word of God is to read slowly. When teaching the Word of God, it is important to both read aloud and to listen to your own voice. Far from being ridiculous, slowly reading the Word of God accomplishes two purposes. First, it allows everyone in the audience both to hear and to meditate on the words. Second, you will immediately notice that the spoken words themselves have a power which resonates throughout the room.
Hearing is a deeply spiritual exercise. Listening to yourself as you read will generally ensure that you maintain the proper pace and that the Holy Spirit moves about the room, ministering to everyone as they simply listen, for the Word of God does not ever return void.
