This letter to the Hebrews, in its practical outworking, results in the detachment of the saints from an earthly, religious system, and attaches them to Christ in heaven... that now things are heavenly and spiritual, and not earthly as a religious system. The people who are tied up with an earthly, religious system, and have not entered into the spiritual values of this, are children, not full grown, not going on, but limited. Before this letter closes it has something to say about: "Let us therefore go forth unto Him without the camp, bearing His reproach" (Heb. 13:13). And that, in the light of the whole letter, is saying: "Let us go outside of what is merely an earthly, traditional system, to have our life with and in Christ alone. A spiritual people, a heavenly people, not of this world, with no links whatever with this world, save the link of testimony to it".
