When a Delta passenger went into cardiac arrest on a plane, Tim Tebow stepped in to pray for him. But many are saying he did the wrong thing.

The Delta crew immediately went to work to try to save a passenger's life after he suffered a major heart attack on board. But while a physician assistant stepped in to administer CPR, Tim Tebow left his own seat to pray for the man.

Tebow bent over the man's distraught wife, hugging and praying with her and her friend. When the plane landed the man was rushed to the hospital. Tebow took the stricken man's wife to the hospital and stayed with her until she got the devastating news that her husband died from the attack.

One of the passengers on board posted about the experience on Facebook.

"I watched Tim pray with the entire section of the plane for this man. He made a stand for God in a difficult situation," the post said.

But many do not share the same sentiment. Even though Tebow prayed with the man's wife, took her to the hospital, and stayed with her until the doctor told them the sad news, many are criticizing him for praying in public.

"Tim Tebow was getting in the way while trying to be a missionary on a plane? What a putz!" said one commenter on an Orlando Sentinel article.

"Prayed? Give me a break. Get out of the way and let modern medicine take care of the sick. Idiot," wrote another.

Some are even claiming he was only being selfish by praying for the man's wife.

"Tim Tebow did nothing, because prayer does nothing. The young medical professional who attempted CPR and actually tried to save the man's life actually DID something. What Tebow did was engage in a narcissistic ritual," said one commenter on a People magazine blog.

Some say the negative comments show first-hand the problems of living in a culture that is increasingly becoming more antagonistic to Christianity.

"Tim Tebow did what any caring person would/should do," one commentator fired back. "He provided what the family needed most at the time-someone to show compassion and caring."
