I have begun to study the idea of 'access to God' as is seen in Hebrews 4:16: Let us then with confidence draw near to the throne of grace, that we may receive mercy and find grace to help in time of need.
It resurfaces in Hebrews 10:19-22: Therefore, brothers, since we have confidence to enter the holy places by the blood of Jesus, by the new and living way that he opened for us through the curtain, that is, through his flesh, and since we have a great priest over the house of God, let us draw near with a true heart in full assurance of faith, with our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.
Clearly, this is one of the benefits Christ secures for us through his work as out high priest. Access to God; who can fathom that?
Thomas Watson touches upon the idea of confidence and boldness the believer has in this quote from A Body of Divinity:
Lifting up the face is an emblem of boldness. Nothing can make us so ashamed to go to God, as sin. A wicked man in prayer may lift up his hands—but he cannot lift up his face. When Adam had lost his holiness, he lost his confidence with God; he hid himself. But the holy person goes to God as a child to its father; his conscience does not upbraid him with allowing any sin, therefore he can go boldly to the throne of grace, and have mercy to help in time of need.
