For you, O LORD, are most high over all the earth; you are exalted far above all gods.

Pray that those who don't yet know Him will recognize the Lord as the Most High and turn from spiritual darkness to worship Him above all else.

And your ears shall hear a word behind you, saying, ‘This is the way, walk in it,’ when you turn to the right or when you turn to the left.
readIsaiah 30:21

As the lost in this people group seek to know the truth of who God is, pray that the Spirit of God will draw them to Himself and guide them in the way they should go.

But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved.
readEphesians 2:4-5

Pray that as people place their faith in Christ, they will remember God's mercy and grace and experience joy as they walk in new life with Christ.

The true light, which gives light to everyone, was coming into the world. He was in the world, and the world was made through him, yet the world did not know him.
readJohn 1:9-10

Pray for those God might send to share the gospel here. Ask that they will grow closer to Jesus and be compelled to share His good news with people who don't know it.
