A West, Texas, congregation gathered for worship in a hayfield Sunday, following last week's deadly explosion at a fertilizer plant.
Wednesday's blast killed 14 people, injured 200, and destroyed scores of homes.
Members of First Baptist Church don't have access to their building because it is still in a blocked off area.
The home of the church's pastor, John Crowder, was among those destroyed. Nevertheless, he still preached from the back of a flatbed truck to about 100 people. He encouraged the crowd to prayer for the rest of the community.
"Beloved when your heart is broken He is there," Pastor Crowder told congregants. "When your world is shaken, He is there. When your home is gone, He is there."
One member of the congregation told local television reporters, "Even if this is a tragedy, I think this is something God has put on hearts to learn from. There is a greater message here."
At least five members of the congregation suffered serious injuries in the explosion.
