"It's like heaven knew I needed you. 10.29.22," Madison captioned several photos from her beautiful ceremony this past weekend.
Madison wore an off-the-shoulder, form-fitted wedding gown with a large train and veil, and Grant, an aspiring pastor, sported a traditional black tuxedo with a bow tie.
The Bachelor alum, who competed on Peter Weber's season, also posted a short video of herself walking down a long, grand aisle outdoors as well as Grant's reaction to his bride.
"Yesterday was the best day of our lives," Madison gushed in her post.
Madison told People that she walked down the aisle to "When God Made You" by NewSong and that she and Grant had chosen his parents' home to tie the knot because it's a "unique and special" place to them.
"And having all our friends and family there means so much," Madison said.
"I have always wanted to get married in the fall and we wanted a short engagement, so it couldn't be more perfect," Madison, who dated Grant for only eight months before accepting his marriage proposal, told the magazine.
Madison and Grant's first dance as man and wife was to "Set of 2" by Brandon Lake, and the wedding guests dined on beef tenderloin and herb roasted chicken.
Madison revealed that she used the same Dallas-based florist as Raven Gates and her husband Adam Gottschalk, and her cake -- the reception's "centerpiece," according to Madison -- was a tall masterpiece featuring a garland of gold leaves and white flowers.

Madison also documented the couple's bridal brunch and rehearsal dinner on Friday before the wedding.
"Truly, none of this would have been possible without the support of our families," Madison told People. "They mean the world to us and we feel so grateful for all of their help during this time!"
Madison revealed Monday on Instagram Stories that she and Grant are headed to their honeymoon in Cabo San Lucas, Mexico after unwinding in Dallas for a couple of nights.
Madison said she's "so excited" for the trip, but even more excited to spend "a lifetime" with Grant.
"We are most looking forward to walking out God's purpose for our life together. We can't wait to get plugged into a local church and host community in our new home!" Madison gushed.
Madison and Grant got engaged on July 31 at The Breakers Hotel in Palm Peach, FL, after a short courtship.
The pair went on to have an engagement party, and Madison celebrated her bachelorette party in Miami, FL, with a "Maddie's Last Slam Dunk" theme, paying homage to Madison's love of basketball.
Madison and Grant previously revealed that they were both waiting to have sex until marriage, which is part of the reason they rushed the wedding.
Grant joked in an Amazon Live session in August, "Let's wrap this up! Let's wrap this up!"
"How quickly can we go?!" Madison added with a laugh.
But Grant explained on a serious note, "It's hard. It's not easy... But we believe it's worth it and God designed that to be so beautiful in marriage. So that's what we're waiting for!"
Madison told Us in August of her upcoming wedding, "We want the wedding to embody our values and beliefs and be the best celebration with all of our people. We want a chic and classy wedding... We are so excited to do life together!"
Going back to when Grant and Madison first met, Grant, a former basketball player who suffered an injury that sidelined him in college, said he saw a picture of Madison after her The Bachelor stint and called her his "dream girl" -- but then nothing happened for six months.
A mutual friend named JD then set Grant and Madison up on a date, although both individuals were a little reluctant at the time and thought the timing wasn't the best.
Grant -- who had been single since 2015 -- said he called Madison up on November 24, 2021 and asked her out on a blind date, and then he met her for the first time on December 3.
"I was overwhelmed with nerves," Grant admitted, adding how he had never seen such a confident and beautiful woman who's also a "dreamer."
The pair's first date was at a Mexican restaurant in Dallas, and Grant called their conversation "electric" and "inspiring" that night.
Once Madison returned home, she told her mother that night that she was in "trouble" and she thought Grant was "The One," which was something she had never said before.
Madison debuted Grant on Instagram in May, writing, "So now y'all know, I got the realist G in town. Grant Michael Troutt, so full of passion and purpose and joy, I am proud I get to do life with someone who loves Jesus and people like you do."
"The past 5 months have been the best and wildest adventure," she said at the time.
"Full of highs and lows but there's nobody else in the world I'd rather do life with... You are my best friend. My favorite hello. My hardest goodbye. There's nobody else in the world like you. Let's keep dreaming, vibing, serving, and loving. G&M."
After competing on The Bachelor in 2020 and having a tumultuous, short-lived relationship with Peter, Madison shared with The New York Post's Page Six in November 2021 it would "take a whole lot of Godly men" for her to appear on a reality dating show again.
In fact, Madison had already turned down a stint on Bachelor in Paradise's seventh season, which aired in Summer 2021, by that point.
"I didn't feel like Paradise was really my scene. Some of my friends went on there and had a great time, so good for them! But it just wasn't my thing," the Alabama native shared last year.
Madison wasn't even sure if starring on The Bachelorette would interest her, as she said it wasn't on her "radar" at the time and "a lot of conversations" would need to be had for her to consider it.
On The Bachelor's 24th season, Madison seemed to be Peter's frontrunner and top pick, but she quit the competition during her final one-on-one date with the pilot. Madison seemed torn up over the fact Peter had been intimate with one or more of his other finalists.
Peter and Madison also constantly questioned if their relationship could make it long-term due to their different lifestyles and motivations.
Peter's mother Barbara Weber claimed Peter loves to party and is generally "spiritual," but Madison claimed to have devoted her life to God. She even graduated seminary school and had envisioned herself becoming a pastor's wife.
Not only was Madison a virgin on the show -- and Peter had sex with Hannah Brown four times in the Fantasy Suite on The Bachelorette's fifteenth season -- but Madison said one of her biggest goals in life is to open an orphanage.
Madison also said she expected her future husband to be the religious leader of her future children, and Peter admitted to the bachelorette his faith could definitely be stronger.
Peter therefore proposed marriage to his last remaining bachelorette and technical winner, Hannah Ann, but then he called off his engagement to Hannah and asked Madison for a second chance.
Madison agreed to try again, but just two short days after Peter and Madison's joint appearance onThe Bachelorseason's After the Final Rose special in March 2020, the pair released separate statements via Instagram announcing they had decided to split and end their revived romance.
Madison told Us in October 2021 that she and Peter no longer spoke and had not been in communication at all. After dating Peter, Madison lived in Dallas and entered a relationship with another man that only lasted about eight months.
