Weible spends most of his professional time writing and lecturing on the phenomenon of Medjugorje, traveling throughout the world and the United States. In the past 23 years, he has lectured on this phenomenon in virtually every major city in the U.S., and most cities in Canada. He has also appeared on numerous national, regional and local television and radio programs. Included are the Mother Angelica Television show, and the Oprah Winfrey Show.
In October, 1985, after hearing of the apparitions, which reportedly take place daily up to the present time and have occurred since June 1981, Weible decided to write an article about them for his four weekly newspapers. It was while viewing a video tape of the apparitions as research for the article that Weible, a Protestant at that time, states he suddenly felt a strong message within his heart that not only was he to write about these events, but he was to devote his life to the spreading of its basic message of reconciliation with God.
