Meanwhile, fellow seminary pal and megachurch pastor Rick Warren has invited all the presidential candidates to speak at his church, and actually shared the church stage with Senators Hillary Clinton and Barack Obama - albeit it was an HIV/Aids church conference and not a worship service.
Warren will join his fellow pro-politics and religion friend Huckabee this spring to address preachers on how to effectively talk about politics and social and cultural issues from the pulpit during a conference on April 7 to 9 in Washington DC.
Warren will address what goes through his mind when he invites political figures to speak from his pulpit, and Huckabee will share about his own experiences of merging the two worlds.
Notably, Huckabee in a recent interview with The Associated Press said he learned to be a politician in church. He said he learned to connect to people, raise money and navigate contentious elections by pastoring a congregation and through a successful bid for the presidency of the Arkansas Baptist State Convention.
In some sense, Osteen also supports mixing religion and politics. The popular pastor agrees with the many influential Christian leaders who have worked hard to push the Christian agenda in society.
"I'm 100 per cent behind them. They're great debaters. They're great at making their points. I think there are times when we need to get involved," he said.
But Osteen noted that what he does not like is when Christian leaders get a label because they become too political.
"That's what I don't like. When it's too politicised," he stated. "There's a fine line there, but I think we can't just sit back and let everybody else express their views. I think it's important that we as believers in Christ express our views."
While Osteen - whose sermons are televised in more than 100 countries, drawing about seven million viewers each week - will not allow the potential next US president to speak from his pulpit, many churches across the nation are welcoming with open arms candidates to theirs.
In a presidential race where being religious is an emblem of honour, candidates in both parties will surely continue to knock on the doors of pastors and their churches, although perhaps not at Osteen's church.
