Colin Hansen asks Trevin Wax, author of Holy Subversion -Allegiance to Christ in an age of rivals: What are the key threats to the church that you believe Christians need to subvert?
Wax lists four in particular (there are some more in his book)
1. A self-centered understanding of salvation that centers solely on personal benefit at the expense of radical grace that transforms our hearts and lives.
2. A church-less gospel that individualizes the Christian life to the point where there is no longer any real reason for a Christian to be part of a church.
3. A worldly understanding of success.
4. A slavish addiction to work, wealth-accumulation, and entertainment.
Wax's book came out in January and there's a very good overview of it on Amazon, by Robert Kellemen.
