This is a book which will help many 21st Century Christians have a better understanding and appreciation of these two subjects. What is ‘sanctification’? And what does the Bible mean by ‘perfection’ and being ‘perfect’? Is sanctification a process we go through, or it is something which is given us by God through Christ? And what about perfection? Is that God-given or do we have to strive towards it-? And is it possible to reach perfection, this side of glory? This are some of the questions Bullinger deals with and answers in his usual through, Bible-based style.
