Godly boldness is not inherited, nor comes from some so-called noble or superior lineage. God can and does embolden His people, no matter how lowly or poor or disadvantaged they may be. We were all lost in sin and degradation and humiliation, until Christ cleansed us with His Own precious blood. He has saved us, and placed upon us His nobility and honor, and a portion of His boldness, by the Holy Ghost, for God's glory, and for our great benefit! The apostle Paul is a key example. He was very bold in his persecution of the Lord's people, but at that time he was aligned with the wicked power structure of Israel, the same one that murdered Messiah. But when Jesus confronted Paul on the road, Paul was struck blind. Ananias went to lay hands on Paul in Damascus, and not only was his sight restored, but he was filled with the Holy Ghost. Immediately Paul began preaching Christ's gospel, and that the Lord Jesus is God manifest in the flesh. This drove some of the local Jews into a rage, and they plotted to kill Paul, but Paul escaped over the wall and went to Jerusalem. Instead of piping down, and laying low, Paul started back up again, proclaiming the Lord Jesus, right there in the place where his former mentors and overseers were headquartered. They too plotted to kill Paul, so he left Jerusalem and went to Caesarea. This pattern repeated over and over throughout Paul's ministry: boldness in proclaiming the Gospel even though dangerous, followed by persecution, followed by Paul going elsewhere to preach. So we see that boldness and prudence are in no way incompatible. This is in keeping with Christ's instructions to His people during His ministry.
