But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building;
But - in contrast to "could not make ... perfect" (Hebrews 9:9).
Christ - of whom all the prophets retold: not "Jesus." From whom the rectification (Hebrews 9:10) emanates, which frees from the yoke of carnal ordinances, being realized gradually now, to be so perfectly in the consummation of 'the age, (world) to come.' "Christ ... High Priest," answers to Leviticus 4:5, "the priest that is anointed."
An - having come forward (cf. х heekoo (G2240)] Hebrews 10:7: here х paragenomenos (G3854)] vividly presenting Him before us) as High Priest. The Levitical priests must retire. Just as on the day of atonement no work was done, no sacrifice offered, or priest allowed to be in the tabernacle while the high priest went into the holiest place to make atonement (Leviticus 16:17; Leviticus 16:29), so not our righteousness, nor any other priests sacrifice, but Christ alone atones; as the high priest before offering incense had on common garments of a priest, but after it wore his holy garments of "glory and beauty" (Exo. 18:29-40; Leviticus 16:29), in entering the holiest, so Christ entered heaven in His glorified body.
Good things to come, х ton (G3588)] - the "good things to come" Hebrews 10:1; "better promises" Hebrews 8:6; "eternal inheritance," Hebrews 9:15; 1 Peter 1:4; "things hoped for" Hebrews 11:1.
By a ... tabernacle - joined with "He entered." 'Through the greater tabernacle.' As the Jewish high priest passed through the anterior tabernacle into the Holiest, so Christ passed through heaven into the inner abode of the unapproachable God (note, Hebrews 4:14). But "the tabernacle" is also the glorified body of Christ (note Hebrews 8:2), "not of this building" (not of the natural 'creation, but of the spiritual and heavenly, the new creation'), the Header the mystical body, the Church. Through this glorified body He passed into the heavenly Holiest (Hebrews 9:24), the immaterial presence of God, where He intercedes for us. His glorified body, as the meeting-place of God and all Christ's redeemed, and the angels, answers to the heavens through which He passed. His body is opposed to the tabernacle, as His blood to the blood of goats, etc.
Greater - contrasted with the small dimensions of earthly tabernacle.
More perfect - effective giving pardon, peace, sanctification, and closest communion with God (cf. Hebrews 9:9; Hebrews 10:1).
Not made with hands - but by the Lord Himself (Hebrews 8:2).
