The Black Panther star died in August at the age of 43 from stage III colon cancer

Chadwick Boseman's widow is speaking out for the first time since the actor's death.

Simone Ledward Boseman delivered a moving tribute to the actor on Monday night at the 30th annual IFP Gotham Awards, saying the Black Panther star "made a practice of telling the truth."

"He is the most honest person I'd ever met," she said during an emotional speech honoring the actor, who received the Gotham Awards Tribute prize. "He actively searched for it, in himself, those around him and the moment. The truth can be a very easy thing for the self to avoid. But if one does not live in truth, then it's impossible to live life."

"So it became how he lived his life, day in and day out," she said. "Imperfect but determined. He was blessed to live many lives within his concentrated one. He developed his understanding of what it meant to be the one, the none and the all. 'A vessel to be poured into and out of,' he'd said."

She continued, "He harnessed the power of letting go, and letting God's love shine through. He realized that when one is able to recognize that when their strength does not come from themself, they rarely mess up. That's what he was doing when he was acting. Modeling for us a path to true fulfillment."

"May we not let his conviction be in vain. May our spirits be fertile soil for God's wisdom to fall upon. So thank you. Praise God," Ledward Boseman added.

She said it was an "honor to receive this award on behalf of my husband," adding it was an "acknowledgment of not only his profound work but of his impact on this industry and this world."

Ledward Boseman cried as she added, "Chad, thank you. I love you. I am so proud of you. Keep shining your light on us. Thank you."

This year's Gotham Awards was a hybrid ceremony with no audience but live presenters at New York's Cipriani Wall Street. Robert Hall Winery returned for its third year as wine sponsor for the event.

Boseman posthumously appears in the Netflix film Ma Rainey's Black Bottom, his final film, opposite Viola Davis

Ma Rainey's Black Bottom is based on August Wilson's 1982 play about the "Mother of Blues" Ma Rainey (Davis) and her experience with white management at the time. The movie takes place in 1927 Chicago and explores the racial tension in the music world as white record executives profited off of Black artists.

Boseman died in August at the age of 43 from a private four-year struggle with colon cancer.

In November, Netflix confirmed its plan to campaign the late star as the lead actor in the film. Netflix will also campaign him for supporting actor awards for his turn in Spike Lee's Da 5 Bloods last summer.

Should he be nominated for Best Actor at the 2021 Academy Awards, Boseman will be the first posthumous nominee in the category since Massimo Troisi for 1995's Il Postino.

If he is nominated for Best Supporting Actor, he would become the third person in Oscar history to do so, following Ralph Richardson in 1984's Greystoke: The Legend of Tarzan, Lord of the Apes and Heath Ledger in 2008's The Dark Knight.

Ma Rainey's Black Bottom is now streaming on Netflix.
