Meyer, who has delivered sermons around the world and written more than 100 books, said she once believed hardships were the result of someone lacking faith.
In a sermon video clip posted on Instagram, the 75-year-old said: "I'm glad for what I learned about prosperity, but it got out of balance. I'm glad for what I've learned about faith, but it got out of balance.
"Every time somebody had a problem in their life, [I believed] it was because they didn't have enough faith.
"If you got sick you, didn't have enough faith. If your child died, you didn't have enough faith,"
"Well, that's not right! There is nowhere in The Bible where we're promised we will never have any trouble.
"I don't care how much faith you have, you're not going to avoid ever having trouble in your life.
"Jesus said, 'in the world, you will have tribulation [but] cheer up, I have overcome the world.'"
A report published in 2003 by the St Louis-Post Dispatch that Meyer's ministry owned a $10 million plane and $2 million home brought into question her personal views on the prosperity-gospel message and the organisation's financial dealings.
Joyce Meyer Ministries was forced in 2007 to defend its "high standard of fiscal responsibility" when it became one of six Christian organisations whose finances were investigated by a Republican senator.
In a letter, Chuck Grassley said: "Recent articles and news reports regarding possible misuse of donations made to religious organisations have caused some concern for the Finance Committee."
Joyce Meyer Ministries was granted accreditation in 2009 from the Evangelical Council for Financial Accountability (ECFA) which stated that - in terms of the ministry's financial accountability, transparency, board governance and fundraising practices - it had met the Council's requirements of "responsible stewardship".
