The Holy Spirit, through Peter, also said God's Word is a seed. The words that I speak to you are spirit, and they are life. Jesus said His words are alive. They contain life. The words in your Bible may look lifeless and powerless.
Seeds do, too.
But they are not without life or power. So, if we are to understand God's kingdom and how He operates, we need to understand seeds. Your physical senses are incapable of judging whether a seed is alive or not. You cannot see, feel, hear, smell, or taste the life in a seed. A seed does nothing until planted.
