'Boldness' in the Bible

And when they had prayed, the place where they had gathered together was shaken, and they were all filled with the Holy Spirit and began to speak the word of God with boldness.

Therefore having such a hope, we use great boldness in our speech,

in whom we have boldness and confident access through faith in Him.

and pray on my behalf, that utterance may be given to me in the opening of my mouth, to make known with boldness the mystery of the gospel,

according to my earnest expectation and hope, that I will not be put to shame in anything, but that with all boldness, Christ will even now, as always, be exalted in my body, whether by life or by death.

but after we had already suffered and been mistreated in Philippi, as you know, we had the boldness in our God to speak to you the gospel of God amid much opposition.
