The Book of Acts ends with Paul awaiting trial, yet preaching the Word as he could from some rented quarter:
He preached God’s kingdom and taught about the Lord Jesus Christ with great boldness (parresia) . . . Acts 28: 31.
There is one word that runs through the entire book of Acts. It is that great Greek term parresia which here is translated “boldness.” However, it is not the ordinary word for boldness. It is a word that puts the emphasis not upon courage—though that lies behind it—but upon a particular kind of courage and boldness.
The word means “courage to speak without fear of consequences.”
Too many Christians (and preachers as well) lack this God-blessed quality which is why so little progress has been made in recent days in evangelizing a nation that is rapidly going down the drain. We complain about the fact that we have been remiss as a nation when it comes to truth, holiness and the like, but we are loathe to do what needs to be done about it, namely, to proclaim the one message that is capable of transforming a degraded society into one that pleases and serves God. Science won’t do it, technology can’t, politics is incapable, and only the Gospel has the power to do so. But if we remain afraid to open our mouths honestly and forcefully—as the preachers in Acts did—things will continue to go from bad to worse.
Read the book of Acts again, focusing upon this bold preaching of the apostles and others, and you will see how it was what made it possible for them to “turn the world upside down” as those opposed put it (Acts 17:6). Actually, they were turning things right side up, but unbelievers always get things upside down.
