An estimated 250 million Christians lifted their voices to God on the 10th anniversary of the Global Day of Prayer which was observed on Sunday.
Participating Christians reportedly prayed in 219 nations. Believers gathered in stadiums, concert halls and in small groups in cities and villages around the world.
The prayer themes for this year included the global financial crisis, the HIV-AIDS epidemic, as well as crime and government corruption.
The global prayer event is inspired by 2 Chronicles 7:14 which reads, "If my people who are called by name will humble themselves and pray then I will hear from heaven and I will heal their land."
"The Global Day of Prayer means that we join with millions of millions of Christians around the world, so spiritually we are connected all over the world," said Roger van Schalkwyk of Cape Town, South Africa.
"We just come together, we just connect and in one spirit praying to one God," he said. "That's when He hears us.
The annual day of prayer observance began in Cape Town, South Africa, in 2000.
