I am so thankful that we don't have to research or know everything there is to know.  God has provided special interests into each of us and John has made it possible for us to share not only what we have learned, but an opportunity to learn from other seekers.  I was truly fascinated and it opened even further, the door of my understanding in this area.  Thank you for being faithful to your calling and sharing what you are learning in this area through videos on U-tube.
