"John is the voice, but the Lord is the Word who was in the beginning. John is the voice that lasts for a time; from the beginning Christ is the Word who lives for ever.
Take away the word, the meaning, and what is the voice? Where there is no understanding, there is only a meaningless sound. The voice without the word strikes the ear but does not build up the heart.
However, let us observe what happens when we first seek to build up our hearts. When I think about what I am going to say, the word or message is already in my heart. When I want to speak to you, I look for a way to share with your heart what is already in mine."
