Hebrews 10:19

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

Here begins the third and last division of the letter: our duty now while waiting for the Lord's second advent. Resumption and expansion of the exhortation (Hebrews 4:14: cf. Hebrews 10:22 here) wherewith he closed the first part of the letter, and prepared the way for his doctrinal argument, beginning Hebrews 7:1.

Boldness, [ parreesian (G3954)] - of speech, 'free confidence,' grouuded on the consciousness that our sins are forgiven.

To enter, [ eis (G1519) teen (G3588) eisodon (G1529)] - 'unto the entering.'

By, [ en (G1722)] - 'in:' it is in the blood of Jesus that our boldness is grounded. Compare Ephesians 3:12. It is His having once for all entered as our Forerunner (Hebrews 6:20) and High Priest (Hebrews 10:21), making atonement for us with His blood continually there (Hebrews 12:24) before God, that gives us confident access. No priestly caste now mediates between the sinner and his Judge. We may come with loving confidence, not slavish fear, directly through Christ, the only mediating Priest. The minister is not officially nearer God than the layman; nor can the latter serve God at a distance, or by deputy, as the natural man likes. Each must come for himself; all are accepted when they come by the new and living way opened by Christ. Thus all Christians are, as to access directly to God, virtually high priests (Revelation 1:6). They draw nigh in and through Christ, the only proper High Priest (Hebrews 7:25).
