Simple, Solid, and Looks Great
Color: Antique Bronze
This is one of those simple things that just works exactly how you want it to.
First off, it looks really nice on the counter. The antique bronze finish has a slightly warm tone that doesn’t look cheap or overly shiny, and the design is clean enough to fit in with pretty much any kitchen style.
Assembly took maybe 30 seconds. You just screw the pieces together and it’s ready to go, no tools or fuss. Swapping out rolls is just as easy, and the top cap keeps everything in place without being annoying to deal with.
The weight is really what makes this stand out. The base is heavy enough that it stays put when you tear off a sheet, so you can actually use it one-handed without it tipping or sliding around. It feels solid and well made, not flimsy at all.
Size-wise, it fits a standard roll easily and still has room for larger rolls, so you’re not fighting to get a new one on.
Overall, it’s sturdy, looks good, and is genuinely easy to use day to day. It’s one of those upgrades that seems small but makes your kitchen feel a little more put together.

One of the best biblical motivational books I’ve read
Format: Kindle
I’ve always enjoyed Dr David Jeremiah’s expository preaching. He has been a faithful steward of God’s word. When I came across this book, I was amazed that he wrote a book to give people a positive attitude in moving forward with the vision and dream the Lord has given us. It’s been an enlightening and delightful read.

Awesome!
Format: Kindle
I love this book. I just completed it and now I'm ready it again with my wife. I love that it is very clear that no matter how old you are, God has a plan for you until He brings you home. I would recommend this book to everyone but especially those ages 50 and above. It was a blessing not only for how I will live the rest of my life here on earth but also helping me to understand better and appreciate more my eternal future. I have already and will continue to recommend this book to many I come in contact with and my clients.

Aging does not necessarily lead to retirement from serving God. Every Day is a new opportunity.
Format: Kindle
In our present world, the Church is experiencing a mega-change approach in how it members view the Bible, morality, service to God and man, prayer, and salvation itself. We all struggle with what lies in the future for us, how do we worship, what do we do with our spiritual gifts, and should we modify our relationship with God to fit comfortably with modern times and processes?
It is becoming more acceptable within the Church to practice a reduced moral ethic or code, condone deviancy, accept what was unacceptable once and seek satisfaction, stimulation, and the satiation for spiritual thirst and hunger with theatrical, entertainment, grandiose, and electronic boosting of the Word of God.
So much feel good, promises of wealth and health to those who follow the promises of so many televangelists, get rich quick preachers, and give that you might get schemes offer that which simply is not offered in Scripture.
Doctor Jeremiah offers sound, Bible-based direction for growing spiritually in this troubled, deceiving world. God is not finished, we are not finished, the Gospel is more than sufficient for the times we live in. If we are bored, if we slumber, if we have become dull, acceptant of sin, and are no longer interested in being light to a dark world, read this book.
Perhaps it is time to confess our sins and be filled once again with the Holy Spirit. Read Doctor Jeremiah's words and let them speak to your hungry soul.
