The sound of the gavel opening the Republican National Convention on July 31, 2000 was not really the sound of the gavel. When doing sound tests, the audio engineer for the convention discovered that the noise the gavel actually made was not impressive enough to fill the huge hall in Philadelphia, so he pre-recorded an "ideal gavel sound" that was played over the loudspeakers when the moderator struck the desk with the stand-in gavel.
The gavel served as a switch to trigger an "electronically reproduced gavel pulse."
In a similar way, all of us need the help of the Holy Spirit to faithfully witness to others. Only the Holy Spirit can help the message of our witness resonate in the hearts of others, and bring them to understanding about how incredible Jesus has been to us.
"And hope does not put us to shame, because God’s love has been poured out into our hearts through the Holy Spirit, who has been given to us."
Romans 5:5
