This book is the fruit of the author's many years of searching for a biblical understanding of the source of the holy life of believers and spiritual transformation into the image of Christ. Honest, deeply rooted in Scripture, she lovingly teaches us that the motivating force in the pursuit of holiness is not a sense of duty or even the fear of hell, but only gratitude to God for the work of Christ, done for us and given in the revelation of the Gospel. What only is this obedience is acceptable to God and can bring joy to our hearts, and the Holy Spirit both works in us and enables us to work. And that only in daily trust in Christ do we find a true and solid basis for striving for the spiritual transformation to which the Apostle Paul calls us.
