Pray specifically for the Lembak of Indonesia

During those many days the king of Egypt died, and the people of Israel groaned because of their slavery and cried out for help. Their cry for rescue from slavery came up to God. And God heard their groaning, and God remembered his covenant with Abraham, with Isaac, and with Jacob.
readExodus 2:23-24

As the lost among them labor, groan, and cry out under false religions and sin, pray God will have mercy on them and hear their cries, that He will be their Rescuer from the kingdom of darkness and bring them into the kingdom of light.

For the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own passions, and will turn away from listening to the truth and wander off into myths.
read2 Timothy 4:3-4

Pray that the lost will be open to the truth of the gospel and turn from false teachings and myths to the sound doctrine of Christ in faith.

I give them eternal life, and they will never perish, and no one will snatch them out of my hand.
readJohn 10:28

Pray that as people place their faith in Christ, they will have assurance of eternal life, knowing that no one can snatch them out of the loving hand of Jesus.

To that end, keep alert with all perseverance, making supplication for all the saints, and also for me, that words may be given to me in opening my mouth boldly to proclaim the mystery of the gospel.
readEphesians 6:18b-19

Ask God to give believers He sends to the lost of this people group the boldness and clarity to proclaim the mystery of the gospel in a way that people can understand.
