Is salvation found in grace alone or in grace plus legalism?
Salvation is found in grace alone, not in grace plus legalism. The perversion confronted in Galatians added law, legalism, and works to Paul’s Gospel of Grace, but the testimony is that believers find salvation in grace and grace alone, apart from legalistic additions.
Les teaches that Galatians addresses churches being bombarded with a perversion of the Gospel. Paul says it is not a completely different Gospel but a perversion: they were adding law, legalism, and works to Paul’s Gospel of Grace. Les rejoices when people come out of legalism and realize it is in grace and grace alone that salvation is found. This is the theme as Paul defends his apostleship.
