BIRMINGHAM, Ala. (WIAT) — Hannah Marlin always knew her son was a special gift from God.

Now, an adorable video of John David saying his ABCs with pure joy is spreading his gift around the internet.

“I am just so amazed at the wonderful feedback we have received from this video that we never expected to happen,” Marlin said. “The Lord has blessed me with this wonderful ball of pure joy that I get to raise!”

In the video, John David repeats the letters, but he gets a little stuck on “W.” When he finally gets it and zips on to “Z,” his sweet little face lights up with happiness.

“John David doesn’t know a stranger,” his mother said. “He will wave and hug and high five anyone he sees and meets. He is fearfully and wonderfully made with a never ending amount of love and joy and happiness.”

We promise, the video will warm anyone’s heart. You might even need tissues if you’re susceptible to his unparalleled sweetness!

In even cuter news, the viral video is helping other kids learn their ABCs along with John David.

“John David is gonna change the world someday, and he doesn’t even know it!” Marlin said in the caption to the video she uploaded to YouTube.
