Yes I have read them many many times. It's important to understand the circumstances surrounding their creation for so many Christians do not.
There was no Western Judeo-Christian civilization in existence and no point of view even remotely resembling what we enjoy today in the first century outside of the apostolic church when those books were written.
The historical period that passages like Hebrews 6:4-6, the Epistle of Jude, etc... were written in and initially for was a very dark pagan period of history at the very beginning of the Early Christian expansionary period. Gentile pagans would accept Jesus Christ as savior and then change their mind and go right back to the pagan temple prostitutes and demonic activities.
But even worse, they began syncreting (e.g. mixing) Christian theology with paganism and the Gnostic thought that existed in the first century and forming heretical communities in which they engaged in all manner of debauchery. Worse yet they begin infiltrating Christian assemblies and attempting to take control of them and mislead people away from orthodox Christian teaching into their immoral debauchery. These are the people that created Christian Gnosticism that warred for souls against orthodox Christianity during the second and third centuries before the Council of Nicaea convened and for about 150 years it was not certain which side would win (not known by secular historians of the era anyways).
Trying to extrapolate that to Joel Olsteen is a pretty sorry exercise for Joel is not one those the Biblical authors were referring to.
Joel Olsteen's public published statement of faith is completely orthodox:
What We Believe
The Bible: We believe the entire Bible is inspired by God, without error and the authority on which we base our faith, conduct and doctrine.
The Trinity: We believe in one God who exists in three distinct persons: Father, Son and Holy Spirit. We believe Jesus Christ is the Son of God who came to this earth as Savior of the world.
Salvation: We believe Jesus died on the cross and shed His blood for our sins. We believe that salvation is found by placing our faith in what Jesus did for us on the cross. We believe Jesus rose from the dead and is coming again.
Water Baptism: We believe water baptism is a symbol of the cleansing power of the blood of Christ and a testimony to our faith in the Lord Jesus Christ.
Communion: We believe in the regular taking of Communion as an act of remembering what the Lord Jesus did for us on the cross.
Growing Relationship: We believe every believer should be in a growing relationship with Jesus by obeying God's Word, yielding to the Holy Spirit and by being conformed to the image of Christ.
He would have fit right into the early Christian church not against it.
Historical sidenote: By the early 4th century, Gnostics were kicked out the church and officially forbidden to meet, by the mid 4th century their books were widely banned and by the late 4th century Gnosticism carried a death penalty in the Roman empire.
Warning: Also, don't confuse Christians struggling through the sanctification process (saved but not perfect), struggling with addiction, who fell into an immoral relationship and is needing church discipline to come out of it, missing the mark on some theological points after salvation they need to correct (which happens to everyone as they grow in the knowledge of Christ), or similar life issues with the ones the authors of Hebrew, Jude, etc... were targeting for to do so is unscriptural.
