The power of our WITNESS comes from the Holy Spirit (Acts 1:8). It is the Holy Spirit that causes us to boldly speak the word of God and then through the proclaimed Word causes haters to repent and glorify the Son of God!
Consider the following verses:
“And now, Lord, behold their threatenings: and grant unto thy servants, that with all boldness they may speak thy word,” Acts 4:29
“And he spake boldly in the name of the Lord Jesus, and disputed against the Grecians: but they went about to slay him.” Acts 9:29
“Long time therefore abode they speaking boldly in the Lord, which gave testimony unto the word of his grace, and granted signs and wonders to be done by their hands.” Acts 14:3
The source of that boldness comes from the Holy Spirit.. Acts 4:31: “they were all filled with the Holy Ghost, and they spake the word of God with boldness.”
We are filled with the Holy Ghost to boldly speak the word of God no matter the cost.
“Although the action of witnessing in such environments can bring severe punishment or even death, the disciples were summoned to boldly witness and confess Christ.”
