Paul was so obviously immediately converted by meeting the vision of Christ on the Damascus Road that it should not require a diagram to demonstrate the fact.
I don't know how you looked at the Happy Heralds web site, but if you go to Post #189 on this theme, and click on the article title "VI. BAPTISM OF DISCIPLES OR WATER BAPTISM" that will take you directly to the paper.
Scroll to the bottom of the paper to find a link back to the other baptisms, on which page at the top is a sort of directory to ther segments of the site.
Thanks for the web site directions, I will check it out.
