Pray specifically for the Ngalum of Indonesia

But your iniquities have made a separation between you and your God, and your sins have hidden his face from you so that he does not hear.
readIsaiah 59:2

Pray that those who are separated from God will turn to Him in humility and repentance, seeking His forgiveness and the restoration of a right relationship with their Heavenly Father.

Then Job arose and tore his robe and shaved his head and fell on the ground and worshiped. And he said, ‘Naked I came from my mother’s womb, and naked shall I return. The LORD gave, and the LORD has taken away; blessed be the name of the LORD.’ In all this Job did not sin or charge God with wrong.
readJob 1:20-22

Pray that those who mourn will worship God in the midst of their suffering and loss, recognizing He is the source of all good things and that He is worthy of their praise and trust.

The LORD is my chosen portion and my cup; you hold my lot... indeed, I have a beautiful inheritance.
readPsalm 16:5-6

Pray that as people place their faith in Christ and face hardship, they will remember that God is their portion and cup and that He has a beautiful inheritance for them.

In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit, who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory.
readEphesians 1:13-14

Pray that God will work through believers near and far in bringing the lost to Himself, giving them what they need to do the task He has set before them, and helping them rest in Him because He has given them His Spirit.
