I used to listen to some of the teachings back in the 80's and early 90's and I found that there was very little teaching on the grace of God. This may have changed, because a lot of believers are waking up to the revelation of the love, grace and life of God that is in us now in Christ and living completely dependent on what Christ has done by grace through faith.
Back then there was a lot of condemnation and works being preached. Confessing the word became a "work". Believing God became a "work".
This may have changed as you can't through everyone into the same pool nor judge people from something 20-30 years ago that they believed. We are all growing in the grace and knowledge of the Lord.
Us Christians are the only group that actually kill our wounded or tear apart the ones in the body of Christ with us. It's a complete shame and we "hide" the bitterness, hatred and malice we have under the disguise of "defending the faith" when in reality we could be just "defending our church teachings and traditions".
