It was a typical Sunday morning at Woodhaven Baptist Church in Ocean Springs.
Families gathered to sing, give praise, and hear the word of God.
But this Sunday's service was a little bit different.
" The bible teaches that a Christian has a biblical responsibility when it comes to government," Reverend Sam Johnson says.
Johnson took the opportunity to speak out about gay marriage during his sermon.
He says he wants to remind people about what he calls their moral obligation.
"I'm not going to tell you how to vote, but the scripture says if you chose evil, you live by that evil choice," Johnson says.
Reverend Johnson says when Christians go vote on Tuesday, they should keep the teachings of the bible in their minds, and remember to check yes on the constitutional amendment banning gay-marriage.
Church Members we spoke with say they plan to follow Johnson's advice.
" I am going to vote my conscience. My conscience says a marriage is between a man and a woman and that's it," Church member Gary Shirley says.
"Just the fact of raising your kids, that's going to be something they're going to start teaching in schools that a marriage is now between a man and a man. I don't want my kids believing that," Church member Lowel Clements says.
Church members say they understand not everyone agrees on this issue, but they say that's not going to stop them from speaking their mind.
"God gave us a choice. That's their choice. This is mine," Church member Charlotte Dykes says.
