At least very few of them. Our family has been affiliated with New Life Church Louisville for over 43 years and in that time we truthfully have had very few Church Problems! What we have had are problems brought to church by individuals who have had problems, thereby, to some degree, making it our problem. As I think about those incidents I can see that most of them were because of Ignorance or Disobedience. They either did not know the Word well enough to know how to deal with their problems or they were purposefully disregarding the statements of Scripture and disobeying what it says!
If only our eyes were open to see what all Jesus has provided for us through His atonement (Ephesians 1:16-23) we would have even fewer problems! In this life, in our fallen world, we are going to have problems, difficulties, persecution, etc. Jesus knew that and that is why the atonement, His Word, and His plans have been given so that we would know WHO we are IN Him and WHOSE we are in this life. We are His Ambassadors working with Him to advance His Kingdom on earth today!
The source of many of our problems is not only Satanic attacks but the flesh. By flesh we mean areas of our life not yet submitted to the Lordship of Jesus Christ, and all of us have some of these areas. Example: worry, doubt, fears, anger, grudges and the list goes on. And when we participate in the church, or society in general, we bring all these things, and their derivatives, to the church and our environment. But surrender to Jesus and the application of His Word through the work of the Holy Spirit can deliver, and free us which then positively affects all those around us!
