Pray specifically for the Ndamba of Tanzania

Every word of God proves true; he is a shield to those who take refuge in him.
readProverbs 30:5

Pray that those who don't yet know God will trust the flawless Word of God and seek refuge in Him, finding hope and salvation instead of remaining in spiritual darkness.

You adulterous people! Do you not know that friendship with the world is enmity with God? Therefore whoever wishes to be a friend of the world makes himself an enemy of God.
readJames 4:4

Pray that the lost will be convicted of their friendship with the world, which is hostility toward God, and that they will turn from their sin and embrace the grace and mercy of God through Christ Jesus.

Delight yourself in the Lord, and he will give you the desires of your heart.
readPsalm 37:4

Pray that as people place their faith in Christ, they will delight themselves in the Lord, trusting Him to give them the desires of their hearts.

"Whoever believes in me, as the Scripture has said, ‘Out of his heart will flow rivers of living water."
readJohn 7:38

Ask God to raise up believers and sustain them as they cross cultures to share hope with those who need it. Pray that many might come to know Christ and that streams of living water will flow from their hearts so they will never thirst again.
