Hebrews 7:26

For such a high priest became us, holy, guileless, undefiled, separated from sinners, and made higher than the heavens.

Here is the ultimate superiority of Christ, his sinless and perfect character; all the other arguments are true, but this is the climax. The use of the words "became us" is a reference to our human sense of what is fitting and appropriate and indicates that, even from a human point of view, Christ is not lacking in any quality that is either needed or desirable in his incomparable office as our high priest. "Separated from sinners" means that Christ is no longer vexed by the presence of evil men; he has ascended where they cannot go. The Levitical priest dwelt apart in a separate house for a week prior to the day of atonement; and there may be a reference here to the fact that Christ is separated from sinners, not for merely a week but for all eternity. Christ will confront sinners only once more on the great and dreadful day of judgment when the two classes of sinners, embracing all mankind, shall appear before him for the assignment of their respective destinies.

Made higher than the heavens is interesting because of its difference from the expression in Mark 16:19, where it is said that Jesus was received "up into heaven," and from that in Ephesians 4:1, where it affirmed that Christ ascended "far above all heavens." There could be no difference in the places to which it is said that Jesus has gone. They are one. "Into heaven" means into the presence of God; and "far above all heavens" means far above and beyond all the limitations of sense.
