"On their release, Peter and John went back to their own people and reported all that the chief priests and elders had said to them. When they heard this, they raised their voices together in prayer to God. 'Sovereign Lord,' they said 'you made the heaven and the earth and the sea, and everything in them.'" NIV translation
After their release, Peter and John went back to the people. Upon hearing what happened, the people lifted up their voices in prayer. Is that the first thing that we do? They begin their prayer by saying that God has made everything. Since God made everything, He is in control. There is comfort just in knowing that.
"You spoke by the Holy Spirit through the mouth of your servant, our father David: 'Why do the nations rage and the peoples plot in vain? The kings of the earth take their stand and the rulers gather together against the Lord and against his Annointed One.'" NIV translation
The friends of Peter and John continue their prayer here.
They quote David and Psalm 2. In this Psalm, David is asking God why the authorities plot in vain against the chosen of God.
That is probably a question that we, as believers, ask ourselves today. Does it seem to you that sometimes those around you are ganging up on you to beat you down because of your faith? When those times occur, hold tight to the fact that God is in control.
"'Indeed Herod and Pontious Pilate met together with the Gentiles and the People of Israel in this city to conspire against your holy servant Jesus, whom you anointed. They did what your power and will had decided beforehand should happen. Now, Lord consider their threats and enable your servants to speak your word with great boldness. Strectch out your hand to heal and perform miraculous signs and wonders through the name of your holy servant Jesus.'" NIV translation
The people are still praying after the return of Peter and John from the religious authorities. In the first line of this passage, we see that it was the fault of all people that Jesus was crucified. (Notice it says the Gentiles as well as the people of Israel.) It goes on to say that the crucifixion of Jesus was God's decision and His will. The group goes on to pray for Peter and John and asks for God to give them boldness as well as to use His power for signs. When faced with persecution, do you turn to God and ask for boldness to speak and God's power to be demonstrated? That, my friends, is where the victory comes from.
