Schreiner extends the atonement more than what it was intended

 Reading through Schreiner's book it is clear that he believes not the gospel and that he believes that the extent of the atonement is more than what God has promised in eternity past. Another error of Schreiner's view is that it makes justification an eschatological event. He still believes justification to be a declaration, but this declaration is what happens on the last day. Believers are not declared righteous because of what Christ did on the cross for them. Schriener seems to believe that one's assurance is based on their continuing in their faith. Works righteousness is ultimately Schreiner's belief on justification by faith.
