Are the Osteens evangelical outliers?

Recently Victoria Osteen, wife of pastor Joel Osteen, made some comments that concerned many Christians. Apparently, she stated that worship was not for God but for the worshiper, that when people obey God, they should do it for themselves (although she later revised some of these comments). 

For many evangelicals, the Osteens are on the periphery of Christianity. They represent the “prosperity gospel”—a message that claims that God will bless the faithful with financial gain. Prosperity preachers often live extravagant lifestyles and point to their wealth as evidence of their message. They often quote biblical passages, taking them very literally, to further their claims that God’s desire is health and wealth.

Many evangelicals, however, assert that God doesn’t work in this way. Faithfulness to God doesn’t mean blessings from above, especially in such worldly pursuits. They try to distance themselves from the prosperity gospel, claiming that it doesn’t represent Christianity but a misunderstanding of it.
