'Boldness' in the Bible

but Christ as a son, over his house; whose house are we, if we hold fast our boldness and the glorying of our hope firm unto the end.

Let us therefore draw near with boldness unto the throne of grace, that we may receive mercy, and may find grace to help us in time of need.

Having therefore, brethren, boldness to enter into the holy place by the blood of Jesus,

Cast not away therefore your boldness, which hath great recompense of reward.
