I tend to avoid assessing the fruit [or lack there of] of a person’s ministry based on “gut feelings” - I am sure God is not honored when you belittle the ministry of one of God’s preachers based on your “gut”.
Where did I belittle the ministry of John MacArthur? I’ve listened to him for hours and find him to be right on target most of the time. However, I doubt he has had much effect in converting the unsaved. Can you prove otherwise?
