In the Old Testament the word “boldness” is found but a few times. The root meaning is a place of refuge; then to take refuge; then to be confident, sure, without care. In the New Testament the word comes from two smaller words having the meaning of “all” and “to flow, to run like water.” Together this compound word has the meaning to be outspoken, frank, even blunt; to be confident in utterance, and bold in spirit and demeanor. Sometimes the King James translates this word as confident.
The Lord Jesus was always bold in his preaching and teaching. “For he taught them as one having authority, and not as the scribes” (Matt. 7:29). Jesus even said, “I spake openly (boldly) to the world: I ever taught in the synagogue and in the temple, whither the Jews always resort; and in secret have I said nothing” (John 18:20). There were times when Jesus spoke in parables (John 16:25) and did not walk openly or boldly among the Jews (John 11:54) because his hour was not yet come. But Jesus always insisted that he told them openly that he was the Christ, and that the works which he did bore witness of him, even though the Jews complained that he made them doubt because he did not teach plainly, boldly, without ambiguity (John 10:24–25). When Jesus died on the cross, taking our sins out of the way, and spoiling principalities and powers, “He made a shew of them openly, triumphing over them personally” (Col. 2:15). The work of Jesus was not performed in a corner, but openly, publicly, boldly, without any concealment, hesitancy, or ambiguity.
