Pray specifically for the Ayamaru of Indonesia

For at one time you were darkness, but now you are light in the Lord. Walk as children of light.
readEphesians 5:8

Pray that those who are lost will turn from the darkness they are walking in and embrace the light, becoming children of light who bear fruit in every good work.

The God who made the world and everything in it, being Lord of heaven and earth, does not live in temples made by man, nor is he served by human hands, as though he needed anything, since he himself gives to all mankind life and breath and everything.
readActs 17:24-25

Pray that the good news will reach everyone in this people group and that many will come to know and serve the one true God who made the world and everything in it and lives today.

The point is this: whoever sows sparingly will also reap sparingly, and whoever sows bountifully will also reap bountifully.
read2 Corinthians 9:6

Pray that as people place their faith in Christ, they will remember the principle of sowing and reaping, and be generous in their giving and serving, knowing that they will reap a generous harvest.

Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort, who comforts us in all our affliction, so that we may be able to comfort those who are in any affliction, with the comfort with which we ourselves are comforted by God.
read2 Corinthians 1:3-4

Pray that as people hear and believe the gospel, they will serve others in Jesus' name, and the lost will have an opportunity to hear and respond to the gospel.
