Kevin Costner and Whitney Houston in “The Bodyguard.” (WARNER HOME VIDEO)

“I urge us all today ... to dry our tears, suspend our sorrow, and perhaps our anger, just long enough to remember the sweet miracle 
of Whitney,” the actor said, before sharing the story of how Houston came to be in the 1992 film “The Bodyguard.”

Costner said he and Houston did not seemingly have a lot in common (“She’s a girl, you’re a boy. You’re white, she’s black.”), but they bonded over their upbringing in the Baptist church. He persuaded the studio to postpone filming “The Bodyguard” for a year while she toured, but Houston still had to prove herself during a screen test:

“Whitney would have to earn it. That was the first time I saw the doubt. ... Whitney was scared. The biggest pop star in the world wasn’t sure if she was good enough.”

Costner painted a picture of an extremely talented woman who still wondered, “Am I good enough?”

“It was the burden that made her great and the part that caused her to stumble in the end,” he said. “Whitney, if you could hear me now, I would tell you you weren't just good enough. You were great.”

He continued: “You weren’t just pretty, you were as beautiful as a woman could be. And people didn’t just like you, they loved you.

“So off you go, Whitney. Off you go, escorted by an army of angels to your heavenly Father. And when you sing before Him, don't you worry:  You'll be good enough.”
