Pray specifically for the Giay of Vietnam

For all the gods of the peoples are worthless idols, but the LORD made the heavens.
readPsalm 96:5

Pray that those who are seeking after worthless idols will not be satisfied until they seek the truth and find it in Christ.

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.

Glory in his holy name; let the hearts of those who seek the LORD rejoice!
readPsalm 105:3

Pray that as people place their faith in Christ, they will glory in His holy name and that their hearts will rejoice.

Jesus said to them, "I am the bread of life; whoever comes to me shall not hunger, and whoever believes in me shall never thirst. But I said to you that you have seen me and yet do not believe."
readJohn 6:35-36

Praise God for the things such as bread that He has provided as natural conversation bridges to the gospel. Pray that believers will use any bridges He provides to share the gospel with those who do not yet know the good news.
