Oswald Chamber's. Is a minister of deep Biblical truths,as deep as the oceans canyons. HE'S an example of how deep the HolySpirit can take you in knowing Christ Jesus.I never pass up an Oswald Chambers book. This complete wools if an all in all devotional in one,plus the CD-Rom is excellent!!!!!!.It can keep the Deepest Pastor busy 24/7 in deep,rich,study with The Lord!
If I can only have one other book apart from the Bible, it will be Oswald Chamber's Complete Works! I rate this work far higher than any other I have come across, for the way it has transformed and helped me in understanding what it is to be a Christian.
