Pray specifically for the Sinhalese of Thailand

For the LORD knows the way of the righteous, but the way of the wicked will perish.
readPsalm 1:6

As many look for hope in worldly pleasures, pray they will hear and accept salvation through Christ, turn from destruction, and experience joy in the way of righteousness.

Lead me in your truth and teach me, for you are the God of my salvation; for you I wait all the day long.
readPsalm 25:5

Pray that the gospel will advance and that God will lead people in His truth, bringing many to salvation.

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.

For we do not want you to be unaware, brothers, of the affliction we experienced in Asia. For we were so utterly burdened beyond our strength that we despaired of life itself. Indeed, we felt that we had received the sentence of death. But that was to make us rely not on ourselves but on God who raises the dead.
read2 Corinthians 1:8-9

Pray that as people hear and believe the gospel, they will be faithful as they walk through trials and will have an opportunity to be a witness to others in this people group of the goodness of God.
