"It's difficult sometimes, but God gave me a talent," Pacquiao said. "He gave me a wisdom and a knowledge."
Although Pacquiao has some conservative social views, he also has ties to progressive American politicians, including Nevada Sen. Harry Reid. The boxer campaigned for the Democratic majority leader during his tough re-election victory over Sharron Angle in 2010.
Pacquiao also visited Obama at the White House last year, discussing basketball and boxing. The fighter says he enjoyed meeting Obama, but didn't share his views on same-sex marriage.
Pacquiao is the fourth of six children born into poverty in the Philippines, and he has four children of his own with his wife. He has spoken out against birth control during his political career, affirming his Roman Catholic faith.
Floyd Mayweather Jr., Pacquiao's only rival for pound-for-pound supremacy in boxing, took to Twitter on Wednesday to tout his own beliefs.
"I stand behind President Obama & support gay marriage," Mayweather tweeted. "I'm an American citizen & I believe people should live their life the way they want."
