“After this prayer, the meeting place shook, and they were all filled with the Holy Spirit. Then they preached the word of God with boldness.” (Acts 4:31)
The word boldness is the Greek word “parresia”. This involves more than confidence; it was a free-flowing, unrestrained boldness. It can also mean "freedom of speech."
Parresia carries nuances that are not easily brought over into English. The person who speaks with parresia will say everything that is on his mind with no restraint, flowing out of his heart with confidence. It involves being frank and honest, hiding nothing and speaking directly to the heart.
Most often it is a word used for public speaking. It refers to speech that is not tailored to make everyone happy but to speak the truth, in spite of what that may cost. It is the courage to speak truth into the ears of others.
Does this boldness of the Holy Spirit abide in and flow through you???
