Galatians

I cannot tell you how many times I have known pastors, elders, and other well-meaning people in their churches brought down by the very thing they are trying to step in and prevent in the life of another person. I have known people to get into affairs with the people they were trying to council out of having an affair. I have known people sucked into crippling gambling addictions who were introduced to the world of gambling when they reached out to help someone caught up in gambling. The same goes for pornography, financial schemes, and other places where the person was never tempted to sin in that particular area until they got involved to help someone struggling. Why does this happen? How can we prevent this from happening.
