Saving faith and repentance are really two names for one radical turn by which one's original course is reversed away from sin and toward God. They are introduced together in both the Shorter and Larger Catechisms. The Catechisms and Confession order these subjects in widely different ways. The Confession deals with faith and repentance after effectual calling, justification, adoption and sanctification, and before good works, perseverance and assurance. Glorification appears in the last two chapters.
Glorification comes at the end, a natural place, since it is part of the consummation.
It is noteworthy that G. I. Williamson, in The Westminster Confession of Faith for Study Classes has actually reordered the Confession's chapters to keep faith and repentance near effectual calling, since they are the immediate and necessary fruits of regeneration. The duty of repentance and faith is treated in question 153, after the lengthy exposition of the law of God. In the Shorter Catechism the order is different still. The questions concerning effectual calling, justification, adoption and sanctification are followed by three questions dealing with the benefits of salvation in this life, at death and at the resurrection. After that a study of the means of grace, the word, the sacraments and prayer, concludes the catechism.
