Every generation has to come to grips with the gospel. The imputation of the righteousness of Christ to sinners--as our whole and only righteousness--has often been under assault in the history of the church. It is in our day in the form of the Federal Vision and the teaching of final justification. Jon and Justin engage with both of these errors today in an effort to clarify and defend the heart of the gospel, which is the righteousness of Christ counted to sinners.
