What began as a movement in South Africa has spread around the globe. In July 2000 and in February 2002, God gave two complimentary visions to Graham Power, a successful businessman and relatively new convert, that Africa would become the "light to the world."
The first stage of inviting Christians in Cape Town, South Africa, to unite in prayer grew to a call to the entire continent of Africa. By Pentecost Sunday, May 15, 2005, the call had been issued to the entire world.
People started praying as the sun rose in the East (New Zealand) and continued in different time zones until the sun set in the West (USA). The planning involved leaders from all 6 continents and included more than 240 countries around the Globe, under the auspices of the International Prayer Council. And the event itself, as people all over the world poured out their hearts in prayer and worship, was a testimony of the moving Sp
irit of God.
About 70 prayer leaders from each of the major regions of the world have committed to continuing with the Global Day of Prayer movement until 2010, in order to build momentum and fill the earth.

In 2007, San Antonio as a city joined this wave of prayer, meeting in the Alamo Convocation Center on Pentecost Sunday, May 27, 2007. More than 1200 Christians from across San Antonio, 
representing dozens of churches and
at least sixteen different ethnic groups joined hearts and hands to honor the LORD and to continue on a journey to unite the Body of Christ in this city.
Prior to the meeting many people joined in ten days of constant prayer. One group of ladies prayed around the city, visiting different churches in every corner of the city each day as well as spending one day praying around churches in the central business district of San Antonio.
During the ten events of the 90-Days of Blessing hundreds of volunteers from more than forty churches fanned out across the city, distributing more than 500 pairs of new tennis shoes to needy children, giving away more than 1000 backpacks to school children in the areas of our city where the need is greatest. These volunteers painted park benches and tables in public parks, cleaned up streets in housing projects, and witnessed to dozens of people in street rallies. New relationships in the Body were forged, new friendships made, and Christians worked shoulder to shoulder without regard for race, social standing, or denomination. Truly the name of Jesus was exalted and honored.
