A homeless man is learning the true meaning behind "paying it forward" after he gave a woman stranded on the road his last $20.

Kate McClure was driving down Interstate 95 late one night when she ran out of fuel. Unsure of what to do, she got out of her car.

Luckily for McClure, her knight in white shining armor would come in the form of Johnny Bobbitt Jr., who came to the rescue.

"He saw me pull over and knew something was wrong. He told me to get back in the car and lock the doors. A few minutes later, he comes back with a red gas can. Using his last 20 dollars to make sure I could get home safe," McClure said.

Floored with his generosity but without cash, McClure visited Bobbitt the following day to pay him back.  

After returning several more times with cash, clothes and food in hand, McClure discovered his backstory and they formed a close bond.

After discussing Bobbitt's predicament with her boyfriend, Mark D'Amico, the pair came up with an idea to make his life a little bit better.

McClure started a GoFundMe campaign for Bobbitt, hoping to raise enough money for Bobbitt to afford the essentials and to have a stable place to live.

"I wish that I could do more for this selfless man, who went out of his way just to help me that day," she wrote on the fundraising page. "Truly believe that all Johnny needs is one little break. Hopefully with your help I can be the one to give it to him."

Thanks to McClure's touching words, donations poured in, and the campaign raised over $220,000 in just 12 days.

According to the Philadelphia Inquirer, Bobbitt was a former ammunition technician in the Marines and a talented paramedic, who was "smart enough to become a doctor."

Unfortunately, Bobbitt's life went in a downwards spiral when he began taking drugs, which led to an onslaught of financial difficulty. Records show he has a criminal record in North Carolina.

However, D'Amico said when Bobbitt talked about his hardships, he owned up to faults.

"Johnny said, 'Yeah, tell me about bad luck. But don't get me wrong. I'm here because of my own decisions. I got nobody to blame but myself.'"

According to McClure, Bobbitt hopes to move to Robbinsville, New Jersey, and work at the city's Amazon warehouse.

"He definitely has the drive," D'Amico said. "He doesn't want to be on the streets anymore. He wants to be a functioning member of society and not be sitting on a guard rail in Philadelphia."
