Sure ... just because they may be one or a few bad apples ... why dont you go ahead and use that as an excuse to say all the apples are bad.
Would it be right Naruto_ if i said that "Bin laden was responsible for 9/11 attacks, therefore all muslims are murderers". Now would that be wise? Yes or No?
Im guessing your answer is no that it wouldn't be a fair judgment. So you can you say the same thing here? Some might be frauds, but they're part of what Jesus says about the End Time false prophetS and the wolves in sheeps clothing if you've read the Bible.
Instead of looking at the minority, why dont you look at the majority and see the amount of wonderful miracles taking place? Just only today i watched a Christian broadcast of a Benny Hinn crusade in Waco Texas today i think, and it showed briefly some testimoni'es of people who have been healed, one lady had lung cancer and she said how she felt electricity in her body and was just HEALED. The cancer left, a literal lump like tumor.
You know my friend, people can say all they like and be skeptial all they like, but i've had miracles, so i know how real they are. When you experience the true power of Jesus, you learn to not follow what skeptics and scoffers say.
