Good shelf to upgrade my awkward kitchen!
Size: 42 inch 2 Tier
This shelf is exactly what I was looking for for my awkward kitchen in my new house. Don't mind the plywood walls (who knows what the previous owners were thinking 🤣) but anyways, we had this awkward gap between the kitchen counters and the stove, so I got a stainless steel shelf to fill the gap and add some more counterspace, and I found this industrial style pipe shelving, which was the perfect size and height to fit in this gap on the wall and give us more storage/organization space.
It's easy to assemble and hang up, and seems very strong and sturdy. It's a little heavy, but lightweight enough to hang easily. Right out of the box, it was disappointing to see some scuffs in the black paint on the piping, especially for the price. Luckily, the biggest scuff is in a pretty inconspicuous space so it's not a big deal. Definitely not worth returning to see if another one wouldn't have any scuffs (especially since many of the other reviews mentioned scuffs too). It's wabi sabi I suppose 😅
Also, not a single extra screw or hardware was included. Not a big deal, but screws are cheap enough to through in one extra just in case one is missing or lost.
Overall, mostly happy with the purchase. The wood is solid and the shelf looks nice in my kicthen!

Very sturdy but heavy

Easy to put together. A little bit too heavy for Sheetrock. I had to use some bigger screws.
I love the look with my cabinet.

Waiting on the Lord is throughout the Bible. Learn how.
Format: Paperback
This is a must-read, like "My Utmost For His Highest" by Oswald Chambers, "Let Go" by Fenelon or " Your Only Comfort - Devotions for Hope in Suffering" by Charles Spurgeon. Learn to rest, wait, and trust in the Lord for answers.

In Your Season of Waiting? Give it a Chance.
Format: Paperback
I chose to read this book for a book club, as my university now has book clubs. This book is very insightful when it comes to the concept of waiting - as many of us struggle with waiting, and the seasons of waiting we experience. Whether we are religions or not - there are many nuggets of wisdom, and moments of inspiration we can gain from reading this author's book. His journey is also relational in one way or another to many of us. While I have my own religious and spiritual beliefs, however different than the authors, there were will nuggets of wisdom and insight that were helpful to me, as I am in my long season of waiting, and even suffering due to injury/disability/accident, so I was drawn to this book for a book club study, and it did bring a great deal of insight from one human being to another, and in a book study environment, it brought a lot of enrichment, engagement, dialogue, smiles, laughter, connection, depth, relation, etc. It helps you realize that it's very relational, very rich and provides great depth, no matter your beliefs, no matter what part of your journey you are in, and that you're not alone, and that this book can be helpful, and that it's not full of nonsense, it's full of practical guidance and wisdom. I recommend it.

Excellent treatment on the subject of waiting on the Lord

Waiting Isn’t a Waste, The Surprising Comfort of Trusting God in the Uncertainties of Life
by Mark Vroegrop (Wheaton, Illinois: Crossway, 2024), 135 pp. paper, $13.49
Vroegrop’s book Dark Clouds, Deep Mercy was popular partly due to its subject matter: grief and suffering. Now Vroegrop, lead pastor of College Park Church in Indianapolis, is addressing another hot subject—waiting. It is no wonder that it has drawn the attention of Christianity Today, which awarded it one of the best books for 2024. Everyone struggles with waiting. The author writes, “This book is about the ‘gaps of life’ and how the Bible calls us to fill the void of uncertainty by waiting on God” (p. 1). We tend to fill the gaps with fear, anxiety, frustration, or anger (pp. 2, 16, 33-36); Scripture calls us to fill them with hope and trust in God. The stated aim is “to help us take steps in learning to wait” (p. 5), and the goal is to unpack this definition: “Waiting on God when I don’t know what’s true about my life” (p. 5). The book has six subjects, each of which has a chapter devoted to these topics:
• Honestly: waiting is hard
• Frequently: waiting is common
• Thoughtfully: waiting is biblical
• Patiently: waiting is slow
• Intentionally: waiting is commanded
• Collectively: waiting is relational (p. 6)
Waiting is loaded with good quotes such as this one from Ben Patterson: “To wait is to journey in faith toward the things God has promised” (p. 11). Andrew Murray and his devotional classic Waiting on God are liberally quoted. One example: “This is the blessing of waiting upon God, that it takes our eyes and thoughts away from ourselves, even our needs, and desires, and occupies us with our God” (pp. 12-13). The author is quotable as well. Three excellent statements are as follows:
When my desire for control gets the best of me, I frequently turn to three unhelpful and sinful responses: anger, anxiety, and apathy (p. 33).
Waiting requires living by what I know to be true about God when I don’t know what’s true about my life (p. 39).
Rather, my typical response is annoyance at best and anger at worst. You too? Understanding the biblical connection between wait and hope invites us to shift our focus from what’s not true about our lives to what is true about God. In other words, waiting biblically is seeing seasons of delay as opportunities to hope in God (p. 42).
Vroegop often turns to the Psalms for insight and direction, noting that there are 14 psalms that celebrate waiting (p. 30). From Psalm 25 and 27 he draws a four-fold strategy for waiting, forming the anacronym FAST:
Focus: live with a God-centered perspective (Psalm 25:3).
Adore: worshipfully rehearse what you know to be true (Psalm 27:1)
Seek: request God’s help (Psalm 25:16, 17, 18, 20)
Trust: “embracing by faith the contentment and spirited rest that comes from knowing God can be trusted” (Psalm 27:13-14). Trusting is a choice (pp. 75-76).
Vroegop reminds his readers that while we are waiting, the Lord may intervene in ways that are amazing: “I’ve seen problems solved, solutions surface, people convicted, and conflict resolved” (pp. 109-110). These past interventions give us hope for present ‘gaps’” (p. 66).
I was disappointed with the author’s passing references to the Message paraphrase, the Enneagram (p. 3), lighting of candles (p. 69), and Dallas Willard (p. 79). But these slights do not tarnish the excellent treatment on the subject of waiting on the Lord.
