Revd Alfred Cooper was speaking after a magnitude 8.3 earthquake hit the northern coast of Chile, killing at least eight people so far and forcing more than a million from their homes.
Tsunamis flooded several coastal towns, and although the tsunami alerts have now been lifted people are concerned more may occur.
The earthquake, the most powerful throughout the whole world so far in 2015 came a day before Chile celebrates Independence Day, a national holiday.
Revd Alfred Cooper told Premier's News Hour: "It was the strongest earthquake we had this year in the world. We still are thankful to human lives has been minimal.
"There's a lot of prayer in Chile right now, much prayer. And as you know there are many Christians here, a good 20% of the Chilean are evangelical or Pentecostal Christians, so mostly I'd say we have been spared by a lot of intercession.
"Pray that the government will make the right decisions in terms of how best to help... [and] that we have good coordination of the relief effort.
"And let's pray that somehow the Gospel, in the midst of all this pain and insecurity and frustration, spreads."
