Pray specifically for the Sinhalese of Thailand

And the people of Israel went into the midst of the sea on dry ground, the waters being a wall to them on their right hand and on their left.
readExodus 14:22

Pray that the God who split the sea so that the Israelites might pass through would do another great work among these people, softening the hearts of those who remain lost to the good news and saving them from their sins.

“I was ready to be sought by those who did not ask for me; I was ready to be found by those who did not seek me. I said, ‘Here I am, here I am,’ to a nation that was not called by my name."
readIsaiah 65:1

Pray that the lost will be found by God, even when they are not seeking Him. Pray that He will reveal Himself to them in a way they cannot ignore and that they will respond in faith.

And how are they to preach unless they are sent? As it is written, “How beautiful are the feet of those who preach the good news!”
readRomans 10:15

Pray that as people place their faith in Christ, they will be eager to proclaim the good news of peace, knowing that the Lord has called them to this task.

But by the grace of God I am what I am, and his grace toward me was not in vain. On the contrary, I worked harder than any of them, though it was not I, but the grace of God that is with me. Whether then it was I or they, so we preach and so you believed.
read1 Corinthians 15:10–11

Pray that God's people will preach the message of Jesus' death and resurrection and that it will spread among the lost through the selfless witness of believers.
