“Beggars” | Truman Brothers (Official Music Video)

You are God’s beloved child. So is the person next to you in unity, the person facing you in conflict, the person at your head in the workplace, and the person at your feet on the city street. Jesus Christ gave his life for all humanity to save us from ourselves—to save you from your sins and your neighbors from theirs.

We’re each indebted to the Lord for all that we have, and we each depend on him for all that we need. When we cry out unto him for his mercy and support, he answers. And when his children cry out unto us for mercy and support, we must answer.

You have talents, skills, and resources. You came to earth to develop the divine capacity to love and forgive your fellow beings the way our Redeemer has loved and forgiven you. Someone within your influence needs it more than you realize. Be brave. Reach out and provide! Then take a step forward and reach further. Change the world, one life at a time. It will change you into a true disciple and a reflection of Christ.

“For behold, are we not all beggars?” (Mosiah 4:19)

Why Walmart?

Rachel Brand grew up in a small town in Iowa, graduated from Harvard Law School, began an amazing career as an attorney, was appointed to the Department of Justice – and now she’s our EVP of Global Governance, Chief Legal Officer, and Corporate Secretary. Wow! Her teams oversee everything from food safety and healthcare compliance to global security, aviation, and our Emergency Operations Center. Working at Walmart wasn’t something she planned to do, but her advice is to always be open to new opportunities. She saw how passionate we are about doing good for people in the world and wanted to be a part of it. Hear from her in this new episode of The Huddle with John Furner.

LSD May Lead to a New Kind of Medicine

Studies have shown that psychedelics have huge potential for treating a variety of mental illnesses. There’s just one problem: the side effects aren’t exactly subtle. So University of North Carolina researcher Bryan Roth has developed new molecules that could have the same effect without the trip.

What Baldness and Cancer Might Have in Common

Scientists Finally Figured Out Why This River Flows Uphill

In 1869, an explorer found himself in a Utah canyon that, as far as he knew, shouldn’t have existed. The Green River he was traveling down had cut through the Uinta Mountains, and he couldn’t explain why. In 2026, scientists seem to have finally solved the mystery: a giant blob of rock about 200 kilometers below the Earth’s surface.
