Pray specifically for the Citak Asmat of Indonesia

For we ourselves were once foolish, disobedient, led astray, slaves to various passions and pleasures, passing our days in malice and envy, hated by others and hating one another.
readTitus 3:3

Pray for those who seek worldly pleasures instead of God to flee from sin and choose God’s goodness and lovingkindness by placing their faith in Jesus.

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.

Seek the LORD and his strength; seek his presence continually!
readPsalm 105:4

Pray that as people place their faith in Christ and may feel weak in their current circumstances, they will seek the Lord's presence and persevere in the Lord's strength.

For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek.
readRomans 1:16

Pray that God will raise up sons and daughters who, like Paul, will be bold to share the gospel across cultural barriers so that many might receive salvation.
