Acts 4:1-31 . . . It's about being BOLD.  Peter and John give us a wonderful example in these passages about how to boldly speak of our Lord and Savior, Jesus Christ.  They are filled with the Holy Spirit who gives them strength.  They are able to stand up to the rulers, elders, and scribes and literally "take them down" when they boldly proclaim to preach the gospel and heal in the name of Jesus Christ of Nazareth.  The Hebrew leaders were not happy with what they were doing and threatened them to NOT speak or teach in the name of Jesus.  But, being filled with the Holy Sprit, Peter and John did not let that deter them from their mission.  Acts 4:31, "And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Spirit, and they spake the Word of God with BOLDNESS." 

How does this passage speak to us?  We are living in a world where the opposition to God's Word is growing. We must be bold and have the courage to be obedient to God.  He will deal with the consequences of our boldness for Him.  Our boldness to stand up for Jesus Christ comes from the the same Holy Spirit that filled Peter and John.  Bold does not mean loud.  It means not worrying what others think and not hesitating to teach the Word of God to everyone.  Be BOLD and let the Holy Spirit fill you with the courage to speak the Word of God.
