J.K. Melchior Apr 12, 2021 9:40 PM ET Still, helping migrants is “not a crisis and not a problem for us. It’s a beautiful opportunity to share the Gospel,” says Pastor Rosalio Sosa, who runs 14 shelters in Ciudad Juárez and Palomas, Mexico. Carlos Navarro, a pastor at Iglesia Bautista West Brownsville, adds that many migrants “were, psychologically speaking, tortured”—“they say my country betrayed me, Mexico is not treating me good, the United States is not giving me permission to go inside the country, so I think the only solution is God. . . . People are hungry for God.” Mr. Navarro says his church has served more than 8,000 migrants, and he estimates that more than a third of them accepted Christ.
