Well you are not alone. It seems most that have been taken in by the pentecostal/charasmatic doctrines don't see the contradictions.
A friend of mine was advertising this conference on her facebook page a few weeks ago. The guy that leads the conference supposedly has the secrets to healing. She was really pushing everyone to go. So I looked up the guy. I saw he had a cd for sale on how to avoid heart disease by these secrets he would tell you in the cd. Then I saw the guy had had a massive heart attack! I guess the secrets didn't work on him. So I brought this up to my friend and her answer was basically, "So!"
Apparently she couldn't see the contradiction either.
