For we do not want you to be unaware, brothers, of the affliction we experienced in Asia. For we were so utterly burdened beyond our strength that we despaired of life itself. Indeed, we felt that we had received the sentence of death. But that was to make us rely not on ourselves but on God who raises the dead.
read2 Corinthians 1:8-9

Pray that as people hear and believe the gospel, they will be faithful as they walk through trials and will have an opportunity to be a witness to others in this people group of the goodness of God.
