What does the Bible say about prayer and God's response?

In Acts 4:31, we see a powerful testimony of God's responsiveness to the prayers of His people. The apostles had faced threats for preaching Jesus, and instead of seeking to avoid opposition, they prayed for boldness to continue. Their prayer was met with a tangible reaction—'the place was shaken'—revealing that God not only hears but also acts on behalf of His followers. This event serves as a reminder that even when circumstances seem daunting, God remains sovereign and is able to instill courage and strength in His people, assuring them of His presence and support.
