“From start to finish, the whole Christian life is by grace through faith. A new life in Christ commences with faith, continues by faith, and will be completed through faith. To put this another way, the Gospel is for Christians just as much as it is for non-Christians.
We never advance beyond the good news of the cross and the empty tomb… Therefore, the Christian always looks back to the Gospel and never to the law as the basis for his righteousness before God… There is no such thing as performance-based Christianity… Justification is a doctrine for the whole Christian life from start to finish. It is not simply a doctrine for coming to Christ in the first place… Justification is a doctrine to live by each and every moment.”
– Philip Ryken, Commentary on Galatians, p90-92
