Jesus is the high priest of the oath God swore. If we do not draw encouragement and strength from the ability to draw near to God through Jesus' continual mediation, we ought to repent of how much we have taken for granted what God has done in Christ.

The New and Living Way | Episode 18 | Hebrews 7:18-28

For there is a disannulling of a foregoing commandment because of its weakness and unprofitableness (for the law made nothing perfect), and a bringing in thereupon of a better hope, through which we draw nigh unto God.

And inasmuch as it is not without the taking of an oath (for they indeed have been made priests without an oath; but he with an oath by him that saith of him, "The Lord sware and will not repent himself, Thou art a priest for ever)";

And they indeed have been made priests many in number, because that by death they are hindered from continuing: but he, because he abideth for ever, hath his priesthood unchangeable. Wherefore also he is able to save to the uttermost them that draw near unto God through him, seeing he ever liveth to make intercession for them.

For such a high priest became us, holy, guileless, undefiled, separated from sinners, and made higher than the heavens; who needeth not daily, like those high priests, to offer up sacrifices, first for his own sins, and then for the sins of the people: for this he did once for all, when he offered up himself. For the law appointeth men high priests, having infirmity; but the word of the oath, which was after the law, appointeth a Son, perfected for evermore.
