Pray specifically for the Yetfa 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.

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.

Jesus said, ‘Truly, I say to you, there is no one who has left house or brothers or sisters or mother or father or children or lands, for my sake and for the gospel, who will not receive a hundredfold now in this time, houses and brothers and sisters and mothers and children and lands, with persecutions, and in the age to come eternal life.
readMark 10:29-30

Pray that as people place their faith in Christ, they will know that when they make sacrifices to follow Jesus, He is there with them and will bless them abundantly in this life and in the life to come.

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.
