What's more, in the winter of 2006, Hamilton had a dream - "the kind Joseph of the Bible had", according to Third Coast Sports, a company that specialises in church marketing and event planning for sports teams.
Hamilton dreamed that he was taking part in a Home Run Derby in Yankee Stadium.
"I was at the plate, I saw all the guys sitting around and then I was at the plate walking toward them and actually a lady came up and interviewed me," Hamilton said, according to Third Coast. "I was able to show everybody how I was there, why I was there and that was because of God's grace."
And that is exactly what happened nearly two years later.
During last month's Home Run Derby at Yankee Stadium, Hamilton hit 28 home runs in the first round, eclipsing the next closest competitor's eight.
"It's a lousy night to be an atheist," said famous sports journalist Rick Reilly during the broadcast of the Home Run Derby on ESPN.
Though Hamilton would eventually lose to Minnesota Twins' Justin Morneau in the final round, his record-breaking first round was enough to snag him an interview with ESPN reporter Erin Andrews at the Home Run Derby's conclusion.
"It's amazing in the past few years what God has done in my life and how quickly He has done it," Josh told Andrews. "I just really want to thank my Lord and Saviour Jesus Christ for all of this. I just want to glorify Him."
Speaking later with the Seattle Mariners' former All-Star second baseman, Harold Reynolds, Hamilton recalled his dream, noting that he did not know how many home runs he hit or if he had won in the dream.
"[A]nd you know why? It's because God don't care about all that stuff," Hamilton said, according to Third Coast. "All He cares about is me being here. In my dream I got to share Christ with people and tonight that's exactly what I did."
Hamilton's hope is to continue sharing his testimony to more people as the platform he stands on becomes larger.
"I pray the more successful I am, the more people will listen," he told a reporter with Gannett News Service.
Hamilton hit a three-run homer and became only the fifth player since 2000 to have at least 98 RBI in his team's first 100 games.
His team is currently third in the American League West division, trailing the Los Angeles Angels by 10 wins.
