Pray specifically for the Ambai of Indonesia

readExodus 2:23-24

As the lost among them labor, groan, and cry out under false religions and sin, pray God will have mercy on them and hear their cries, that He will be their Rescuer from the kingdom of darkness and bring them into the kingdom of light.

The mountains rose, the valleys sank down to the place that you appointed for them.
readPsalm 104:8

Pray that they will see the hand of God in the beauty and order of the natural world, and that they will worship Him as the Creator and Sustainer of all things.

Seek the LORD and his strength; seek his presence continually!
readPsalm 105:4

Pray that as people place their faith in Christ and may feel weak in their current circumstances, they will seek the Lord's presence and persevere in the Lord's strength.

Jesus said to them, "I am the bread of life; whoever comes to me shall not hunger, and whoever believes in me shall never thirst. But I said to you that you have seen me and yet do not believe."

Praise God for the things such as bread that He has provided as natural conversation bridges to the gospel. Pray that believers will use any bridges He provides to share the gospel with those who do not yet know the good news.
