Justification by faith is an important doctrine because of the kind of person it develops. A person of humility, knowing their righteousness is imputed by faith and not by their ability to follow the law. A person of integrity, who has been open and vulnerable towards God, acknowledging their sin and appealing to his mercy and forgiveness. But not only that, justification by faith has also been designed by God to produce in its adherents a character of true righteousness.
