Pray specifically for the Giay of Vietnam

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.

For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life.
readRomans 5:10

Pray that God will remove obstacles to the gospel so that many will see the hope He offers through the death, burial, and resurrection of His Son, and be transformed from being enemies to being His friends.

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.

And if anyone will not receive you or listen to your words, shake off the dust from your feet when you leave that house or town. Truly, I say to you, it will be more bearable on the day of judgment for the land of Sodom and Gomorrah than for that town.
readMatthew 10:14-15

Pray for God to raise up and send out believers to share the gospel with those in this people group who do not yet follow Christ. Pray that they will be welcomed with open arms so that the people they share with will hear and receive the good news with joy.
