Pray specifically for the Tumma of Sudan

For who is God, but the LORD? And who is a rock, except our God?
readPsalm 18:31

As people look to their own efforts for hope, pray they will have the opportunity to learn and believe in the Lord, who is the only Rock worthy of their faith.

I sought the LORD, and he answered me and delivered me from all my fears.
readPsalm 34:4

Pray for each who becomes a child of God to share the hope of eternity with family and friends.

Unless the LORD builds the house, those who build it labor in vain. Unless the LORD watches over the city, the watchman stays awake in vain.
readPsalm 127:1

Pray that as people place their faith in Christ, they will build their homes in the Lord and raise their children to know and honor Him.

At the same time, pray also for us, that God may open to us a door for the word, to declare the mystery of Christ...that I may make it clear, which is how I ought to speak.
readColossians 4:3-4

Ask God to open doors for believers to share the gospel and help them communicate it clearly so that more people will understand the mystery of Christ and turn to follow Him.
