Pray specifically for the Batak Toba of Indonesia

For the LORD knows the way of the righteous, but the way of the wicked will perish.

Seek the LORD while he may be found; call upon him while he is near.
readIsaiah 55:6

Pray that the lost will seek the Lord while He may be found and call upon Him while He is near, for He is gracious and compassionate, slow to anger and abounding in steadfast love.

Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us, looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before him endured the cross, despising the shame, and is seated at the right hand of the throne of God.
readHebrews 12:1-2

Pray that as people place their faith in Christ, they will remember the testimony of those who went before them, resist sin, and run with perseverance the race set before them, fixing their eyes on Jesus.

And God has appointed in the church first apostles, second prophets, third teachers, then miracles, then gifts of healing, helping, administrating, and various kinds of tongues.
read2 Corinthians 12:28

Ask God to raise up believers who will faithfully proclaim the good news and equip others to do the same.
