Boldness to enter the holy places, through the blood of Jesus. Under the Old Covenant, only the High Priest could enter the Most Holy Place once a year. Now you have permanent access. Not because of anything you've done, but because the blood of Jesus opened the way.
Boldness here doesn't mean irreverence but the confidence of a child who knows: I am welcome. This confidence is your right in the New Covenant. You need no priest, no ceremony, no special moment.
Walk boldly into God's presence today. You are welcome, always.
