Out in Field Service you would meet an extremely 'interested person' and make arrangements for a Return Visit. When the appointed time arrived and you went back to make your RV the 'interested person' would thank you for visiting again and then tell you that they had started attending the church down the street. Then everyone in the car group would groan when you returned to the vehicle and related what happened. Then someone would say, "Satan made your RV for you. Now they may never accept 'the Truth' because you know how strong Babylon the Great is."
I always struggled with events like this because it raised doubts in my mind such as:
Is Satan that much more powerful than God that he can suppress the Truth?
If the Holy Spirit is really guiding JW's then how could this happen?
Why are the churches in our territory growing so fast and our congregation's attendance has either stayed the same or declined? I thought Jehovah was going to speed things up for the Truth.
