Acts 4:24-31, Acts 4:24  (NIV)
When they heard this, they raised their voices together in prayer to God. "Sovereign Lord," they said, "you made the heavens and the earth and the sea, and everything in them.

Prayer was a vital part of life for this group of believers. They prayed:
•    Together                       v23-24a, Matthew 18:18-20
•    Praises                          v24b, Matthew 6:9
•    Prophetically               v25-28, Matthew 6:10
•    For boldness                v29, Matthew 6:11
•    For miracles                 v30, Ephesians 3:20

A church that prays together grows together: Acts 4:31 (NIV)
 After they prayed, the place where they were meeting was shaken. And they were all filled with the Holy Spirit and spoke the word of God boldly.
