To inspire means to fill someone with the urge or ability to do or feel something.
Throughout the course of sports history, there have been many professional athletes who have inspired the masses.
Magic Johnson, Lou Gehrig and Tiger Woods are just a few of the athletes who have inspired others in their respective sports.
Here are the 25 most inspiring athletes in sports history.
Former NFL QB Kurt Warner was one of the biggest underdog stories in American sports history.
He went from sacking groceries at a grocery store, to becoming a Super Bowl winning quarterback in the NFL.
He is an inspiration to all QBs everywhere, as well as another member of this list, Tom Brady.
Warner's story is one that you can hear over and over without it ever getting old.
Pat Tillman was one of the most patriotic athletes that this country has ever seen.
He enlisted in the U.S. Army in 2002, just a year after his fourth season with the Arizona Cardinals.
Sadly, he was killed in Afghanistan from friendly fire in 2004, nearly two years after he joined the military.
Tillman has inspired many for his ultimate sacrifice for his country.
Former Green Bay Packers and Carolina Panthers' defensive end Reggie White had a following nearly everywhere he went.
The Chattanooga, Tennessee native was nearly unblockable on defense, as he racked up nearly 200 sacks in his 15-year pro career.
White was also known as "The Minister of Defense" due to being an ordained pastor and helping bring many to Christianity throughout his life.
NFL Hall of Famer Michael Irvin summed up White the best when he said, "He was a gift from God, and that's all you need to know about Reggie White".
Roberto Clemente was the most inspiring athlete that ever put on a Pittsburgh Pirates uniform.
He was an amazing talent and dominated both in the outfield and at the plate while in the major leagues.
He also was an excellent person off the field as well.
Clemente died in late 1972 when the plane that he was in crashed on the way to help out earthquake victims in Nicaragua.
Texas Rangers' outfielder Josh Hamilton has been to hell and back in his 30 years of life.
The former Tampa Bay Rays draft pick struggled for years with his drug addictions.
Desperate for a change, Hamilton turned to God to help save him from his problems.
Since those dark days, he was won an AL MVP award and has been clean for years.
Ted Williams was one of those people that was a natural at just about everything that they did.
"Teddy Ballgame" was a 19-time All-Star in the big leagues, and was also dedicated to his country through military service as well.
Williams took part in 39 combat missions as a pilot in both World War II and the Korean War.

Lyman Bostock might be one of the most unknown people on this list, but his story is just as good as any other athlete.
The former Minnesota Twins star made news in 1978, when he made an unimaginable offer to then-California Angels owner Gene Autry.
Bostock offered to return his salary for the month of April, after only hitting .150 during that time period, only to have that offer declined and eventually give the money to charity.
Unfortunately, Bostock was murdered later that year, but his enormous act of kindness will never be forgotten.
Former MLB pitcher Jim Abbott was a talented athlete, but he had one glaring problem.
He was born without a right hand.
The ex-California Angels pitcher didn't let this bother him, as he still was able to win 87 games in his 11-year big league career.
The former Lakers point guard was one of the best players to ever play his position.

Ruettiger was deemed too small to ever play football, yet he proved his doubters wrong but not only making Notre Dame's football team, but also getting some playing time as well.
If you've never seen the movie Rudy, I would recommend it for any sports fan out there.
To many, it didn't seem that former NFL player Vince Papale never had a chance to make it into the league.
