Step-by-step explanation:
In Acts 4, we learn about the commitment to a prayer life from Peter and John. After being released from custody, Peter and John gather with the other believers and pray together. Their commitment to prayer is evident in the way they seek God's guidance and strength in the face of opposition. They pray for boldness to continue sharing the message of Jesus, and their prayer is answered when the place where they are gathered is shaken and they are filled with the Holy Spirit.
