The Lord is a stronghold for the oppressed, a stronghold in times of trouble. And those who know your name put their trust in you, for you, O Lord, have not forsaken those who seek you.
readPsalm 9:9-10

Pray that God will help those who are oppressed and without hope to hear the good news of Jesus and trust in Him, for He has never forsaken those who seek Him.

For the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own passions, and will turn away from listening to the truth and wander off into myths.
read2 Timothy 4:3-4

Pray that the lost will be open to the truth of the gospel and turn from false teachings and myths to the sound doctrine of Christ in faith.

It will be said on that day, “Behold, this is our God; we have waited for him, that he might save us. This is the LORD; we have waited for him; let us be glad and rejoice in his salvation.”
readIsaiah 25:9

Pray that as people place their faith in Christ, they will proclaim and rejoice in His salvation.

And through him to reconcile to himself all things, whether on earth or in heaven, making peace by the blood of his cross.
