readPsalm 30:10

Pray that people in the depths of despair and suffering and living outside of relationship with Christ will cry out to the Lord and find help, peace, and joy in Him.

And he made from one man every nation of mankind to live on all the face of the earth, having determined allotted periods and the boundaries of their dwelling place, that they should seek God, and perhaps feel their way toward him and find him. Yet he is actually not far from each one of us.
readActs 17:26-27

Pray that the lost will seek God and find Him, for He is not far from each one of us. Pray that they will have opportunities to access the gospel, learn God's purpose for their lives, and believe in Him.

But you said, "I will surely do you good, and make your offspring as the sand of the sea, which cannot be numbered for multitude."
readGenesis 32:12

Pray that as people place their faith in Christ, they will experience God's presence and protection even in difficult circumstances, knowing that He will make them fruitful.

O LORD, who shall sojourn in your tent? Who shall dwell on your holy hill? He who walks blamelessly and does what is right and speaks truth in his heart.
readPsalm 15:1-2

Ask God to send believers who will go and, with integrity, walk blamelessly and do what is right, speaking truth about the Lord with those who need to learn about His redemption plan.
