For all the gods of the peoples are worthless idols, but the LORD made the heavens.

There is no speech, nor are there words, whose voice is not heard.
readPsalm 19:3

Pray that God will lead them to His Word, and where it is not available, ask that He will raise up those who will produce gospel media in their heart language.

More than that, we also rejoice in God through our Lord Jesus Christ, through whom we have now received reconciliation.
readRomans 5:11

Pray that as people place their faith in Christ, they will rejoice in what God has done for them and will help others know how they can also be reconciled to God.

Jesus said to them again, "Peace be with you. As the Father sends me, even so I am sending you."
readJohn 20:21

Ask God to raise up and send out believers cross-culturally who will go out in His authority and be sustained by His peace as they share the gospel with the lost.
