Pray specifically for the Central Seko of Indonesia

"For it is easier for a camel to go through the eye of a needle than for a rich person to enter the kingdom of God." Those who heard it said, "Then who can be saved?" But he said "What is impossible with man is possible with God."
readLuke 18:25-27

Pray that the lost who think they have everything they need will recognize their spiritual poverty apart from Jesus and turn to Him in faith.

For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.
readRomans 1:19-20

Pray that God will use His creation – the “things that have been made” – to spark a fresh and passionate curiosity among them to draw near to the Maker and that, as they seek Him, He will make a way for them to hear the gospel and receive it with joy.

He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away.
readRevelation 21:4

Pray that as people place their faith in Christ and walk through challenges, they will find comfort in God's promise of a beautiful future when there is no pain or suffering for those who belong to Christ.

But to all who did receive him, who believed in his name, he gave the right to become children of God.
readJohn 1:12

Pray that believers will have the opportunity to clearly share the good news with the lost here, so that all people can be invited to trust in Jesus and become children of God.
