Great book but the pages started falling out
Format: Paperback
This book is very informative and helpful while I navigate nursing school, but after only 6 weeks of use the pages started falling out. I'm careful with the book and I don't even open it everyday but it was poorly made and the pages are not very sturdy.

A Deep and Rich Resource on Christian Life
Format: Paperback
I've been waiting for this book for quite some time when I heard it would be coming out as part of the Dogmatics series. I really appreciate how he structures the book as God's Trinitarian actions towards us, the law-gospel distinction, and our response to Gods' love. Rich. A real treat to read, ponder, and reflect on.

One of the Best!
Format: Paperback
Kelly Kapic is one of the best theological writers of our day. He gears his writings a bit toward scholars, but don’t let that stop you. Accept the challenge of this book and you won’t be sorry. The title of the series (“New Studies in Dogmatics”) might scare off some readers, but don’t allow that to camouflage a great read. Yes, scholars will likely eat it up as a book that shows an artisan at work in their trade, but I say pastors and thoughtful Bible students ought to claim this one as their own.
The only part that might appeal more to scholars than the rest of us is how he loves to delve into some historical personage or creed to illustrate his point. That is only an issue because sometimes that takes more explanation than the point at large he is making. I doubt he can help it. He seems like a walking encyclopedia; a passionate one to be sure, but it is amazing the scope at which he views his subject.
His clearly stated thesis is that “Christian life is a response to the love of God”. Not only does that make sense, especially as he develops it, but it also gave him free reign to write across most of the systematic theology corpus as he desired. That could easily degenerate in a muddled mess that said little, but in his skilled hands it became something really special. In fact, the first chapter on why we need a theology of Christian life shows his clear vision of the argument of this book. For the record, I was bought in part way through that first chapter.
Part Two with its three chapters fills in “the love of God” part of his thesis. He approaches it as love, grace and fellowship. Those three are often thrown about with a perverse shallowness. Not here. It seems that the depths of the heinousness of sin that he so astutely explains is the key to bringing those three out in all their resplendent glory. Here they sparkle.
Next, he has a section that he called an “interlude” on the Law-Gospel distinction. His Reformed orientation comes out strongest here and this section is likely to be the most controversial. In fact, even some Reformed thinkers might quibble with him.
From there, he develops the “response to” part of his thesis. This last section covers Messiah, ego and ecclesia to great effect. That our Messiah is the key is painted with the right significance. The chapter on ego was profoundly done. I thought he brought in current thinking on ego and held it up to Scripture and came up with clear thinking in the process. The two chapters on ecclesia surprised me. I was sure that he was going to champion a certain strain of liturgy, but actually he explained that every worship style is a liturgy. It was convincing to me.
I nominate this book as the theological title of the year. It is that good.
I received this book free from the publisher. I was not required to write a positive review. The opinions I have expressed are my own. I am disclosing this in accordance with the Federal Trade Commission’s 16 CFR, Part 255.

A labor of love
Format: Paperback
Kelly Kapic provides a biblical and theological vision of Christian life—what it means to love and be loved by God—by exploring and explaining the contours of the “life” that is given to the believer as united to Christ, and united to all believers who participate in that same union. The book covers multiple topics one might find in a systematic theology, but seamlessly weaves these through considerations of Christian ethics and corporate worship with clear and accessible prose. Kapic writes charitably as someone deeply immersed in the history of Christian theology and aware of the modern Christian church as expressed through multiple, and sometimes conflicting, traditions. Kapic remains attentive to the doubts of believers and profoundly sympathetic to the reality of those who have suffered abuse under the banner of grace. A remarkable achievement of beautiful orthodox theology. Highly recommended.

Nice Product

Super Handy and So Stylish — A Must-Have for Any Kitchen!
I’m really impressed with the Sinnsally Kitchen Sponge Holder! It’s simple, practical, and makes keeping my sink area neat so much easier. The 2-tier design is brilliant — the top shelf holds my sponges perfectly, while the bottom area keeps scrubbers and brushes organized and easily accessible.
The stainless steel looks sleek and modern, and it has held up beautifully with daily use. Water drains well so everything dries quickly, and cleanup is a breeze. No more soggy sponges sitting around!
Installation was quick and easy — it fits nicely right by the sink without taking up too much space. This little holder has made a big difference in keeping my kitchen tidy.
Highly recommend for anyone who wants a clean, organized sink area with a touch of style!
