An insightful and encouraging read for anyone in their faith journey
Format: Hardcover
The best devotional book that I have read yet! Every morning there is something challenging, encouraging, and well thought out. There is a scripture to go with each day which can help you know where to start when reading your Bible. The analogies are insightful and encouraging to read. It makes you want to grow in a relationship with Jesus and is good for anyone to read. It isn't a high reading level, so it is good for those new to their faith or those who are looking to grow more.

Biblically Rich, Encouraging, and Convicting
Format: Hardcover
I have purchased this book many times since it was first gifted to me. This devotional is rich and encouraging, convicting, understandable, biblical, and always points back to the Word. Each day is titled with a month and day so it’s easy to find your current page regardless of the year. It is wonderful for anyone who wants to grow in their faith whether you’ve just met Christ or have known Him for a little while :)

Encouraging, Uplifting, and Perfect for Our Team!
Format: Hardcover
We gifted the New Morning Mercies devotional to our lead teachers, and it has been such a blessing! Each daily reading is filled with truth, encouragement, and a beautiful reminder of God’s faithfulness and grace. It’s the perfect way to start each day with purpose and peace. 🌿✨
The quality of the book itself is wonderful — sturdy cover, easy-to-read layout, and timeless content that speaks to the heart. Our teachers have loved sharing their favorite devotionals and using them for reflection and prayer throughout the week.
Highly recommend this book for anyone leading, teaching, or simply needing a daily reminder of God’s new mercies every morning. 💛

Best organizer with a water spout to keep them counter dry!
Color: Black - 9.25″, Color: Black - 9.25″
I am thoroughly impressed with this product. I tried a product that goes over the middle of the sink and it blocked everything off and would always fall off in a funny ways. I had no room for my pots and pans and started getting irritated with it. This is up and out of the way has a little spicket to drain off the water and as you can see I got all of my sponge and soaps in the same spot which is wonderful cleaned off my counter beautifully. I chose the color black to blend in with my black countertop and also to look nice and clean on the counter. One of the best organizers I have ever found for a countertop. It's sturdy metal so far seems rust resistant, but I haven't had it long enough to know for sure. Mobilize easily to clean. Fabulous little sink caddy. I highly recommend to those of you that like to be organized and keep your counter nice and dry, and still arrange things so that it can be out of the way.
