One Oklahoma foster mother was reduced to tears after a young cashier, who said he was led by God, offered her a random act of kindness during a very dark moment.

According to KFOR-TV, 20-year-old Nick Tate works as a cashier at a Walmart in Newcastle, Oklahoma. Tate describes himself as a "people person" who loves "getting to talk to people, and hear about their day and just see how they're doing.”

One Friday night, Tate was working the register, when a foster mother with two little girls and a baby began loading groceries onto his station. According to Tate, the two little girls were "just going crazy," prompting Tate to ask the mother if it was "one of those days."

The mother was a new WIC recipient, a federal assistance program for low-income families with children, Tate told KFOR.

"She apologized beforehand. She said 'I have never used WIC before. I don't know how it's going to go,'” he said.

As the mother attempted to juggle the children and the groceries, Tate said the line began to pile up behind her. To make things worse, once the groceries were scanned in, the pair discovered that WIC would not pay for certain things, including certain brands of baby formula.

"We tried to run it again, and the WIC still didn't work," Tate said.

Tate said that at that moment he felt God was leading him to help this needy mother out.

"So, I just felt like God was telling me just to pay for it,” Tate said.

Tate paid the $60 for the woman's groceries, and the formula for the baby. For Tate, $60 is an entire day's wages. The kind gesture reduced the mother to tears.

"I swiped it, and instantly she started bawling her eyes out,” Tate said.

"You never know what God is going to do. Yeah, it might be hard. It might be scary. It might be a day's wage. But, if God is calling you to do it, he's going to have something major for you,” Tate said.

To protect the privacy of her foster children, the mother did not give away her identity. However, KFOR reported that she expressed the young man's kindness on Facebook.
