The reality star, who was recently charged with battery after an altercation with costar Kenya Moore during a reunion taping, is in the hot seat once again.
In an exclusive statement to PEOPLE, Williams, 31, is apologizing for a sermon she gave that contains purportedly anti-gay comments.
"We Christians are supposed to be telling the hooker on the street, the drug dealer ... the gays, the lesbians – we're supposed to be trying to save them and tell them, 'You are worthy,' " she says in a video posted Monday by TMZ.
"My heart was heavy and it's imperative for me to address the issue," Williams says in a video message released exclusively to PEOPLE on Tuesday. "God loves all of his children."
According to TMZ, the sermon was filmed three years ago at Georgia's High Praise Christian Center Ministries.
"The sermon was shown not in its entirety, therefore the message was omitted," Williams says in her statement. "I apologize that those words hurt the LGBT community, my fans and my supporters. Life is a journey and I'm growing every day."
