In the doorbell video, Lavonte Harvey is seen walking up to an Austin home says "this is for you grandma" and starts singing.

That grandmother shared the video with her granddaughter Whitney Cumbo, and she shared it online.

The grandmother said she shared the video because the song lifted her spirits since she recently lost her husband.

"I didn't expect for it to go viral," Harvey said as he explained that he usually sings on his route.

"For me, singing isn't just music," he said. "It's about ministry, its about spreading hope and joy."

Cumbo said his singing warms her grandmother's heart daily.

She shared the video on her Instagram @bossywhit, in which she teaches financial literacy.

Cumbo helped create a GoFundMe for Harvey.

Now, his two-and-a-half-hour commute has been shortened to 30 minutes, after internet strangers donated enough money for him to purchase a new truck.

He also started a new clothing company in hopes to continue to spread more joy.
