I worked on one of TWR's radio programs from 1992-1995. Recently, I met with friends from eastern part of Indonesia Islands that directly asked me about a radio program that had been aired on the shortwave. I asked, "How do you know that I was the one on that program?" He replied, "I remember your name and voice. I became a committed listener and now I'm a Christian!"
So, it was nearly 20 years ago that I worked on the radio program, but just now heard one instance of it's long term impact. Praise the Lord for this!
