The month of March is when the college basketball frenzy called "March Madness" grips America.

The Billy Graham Evangelistic Association (BGEA) understands the excitement spurred by the sport. Nevertheless, it warns Christians that addiction to basketball can be dangerous.

"The tournament itself isn't the issue. It's where it ranks in your life and what kind of toll it takes on your finances. If making tip-off or winning a game begin to trump your personal relationship with Jesus, then that's very dangerous," the organisation says on its website.

"Your yearning for God must supersede all other desires," says evangelist Billy Graham.

He then lists five pointers that Christians should keep in mind during the National Collegiate Athletic Association (NCAA) tourney:

1. Shine for Christ.

"You're still a light even if your team goes dark. As Christians, we are called to look different from the world," he says. "Sure, you can be temporarily glum if your team loses, but don't stay there."

Graham says the sports should only be a hobby, not an obsession. "We've also become obsessed with entertainment and sports and technological gadgets — things that aren't necessarily wrong in themselves, but in time they can keep us from even thinking about God," says Graham.

2. Consider what's really at stake

Graham believes that greed is the root of gambling, and this is something that God warns against. "We need to be on guard against greed... above all we need to make sure our lives are centred in Christ and not on things," he cautions.

3. Personal connections are rare.

People might find themselves making personal connections with star players, but Graham says that "if you ever cross paths, he likely won't have a clue who you are." The only real relationship sports enthusiasts can have is with Jesus Christ.

4. Take note of your heartbeat.

"It's Sunday. Tip-off is at 12:45 p.m., and the preacher is running long. Anxious? Getting agitated? That's a red flag. Anything can become an idol. Even roundball," Graham says.

5. Reserve worship for God.

Lastly, even though athletes do amazing things, people must remember that these talents all come from God. "They're human. They're going to blow it at some point. Unlike our Heavenly Father. So remember to keep your faith where it belongs," Graham says.
