Not forsaking the assembling of ourselves - Επισυναγωγην ἑαυτων. Whether this means public or private worship is hard to say; but as the word is but once more used in the New Testament, (2 Thessalonians 2:1), and there means the gathering together of the redeemed of the Lord at the day of judgment, it is as likely that it means here private religious meetings, for the purpose of mutual exhortation: and this sense appears the more natural here, because it is evident that the Church was now in a state of persecution, and therefore their meetings were most probably held in private. For fear of persecution, it seems as if some had deserted these meetings, καθως εθος τισιν, as the custom of certain persons is. They had given up these strengthening and instructive means, and the others were in danger of following their example.

The day approaching - Την ἡμεραν· That day - the time in which God would come and pour out his judgments on the Jewish nation. We may also apply it to the day of death and the day of judgment. Both of these are approaching to every human being. He who wishes to be found ready will carefully use every means of grace, and particularly the communion of saints, if there be even but two or three in the place where he lives, who statedly meet together in the name of Christ. Those who relinquish Christian communion are in a backsliding state; those who backslide are in danger of apostasy. To prevent this latter, the apostle speaks the awful words following. See at the end of this chapter (Hebrews 10:39 (note)).

June the Fourteenth the Law in the Heart
"I will put My laws into their hearts." --HEBREWS x. 16-22. Everything depends on where we carry the law of the Lord. If it only rests in the memory, any vagrant care may snatch it away. The business of the day may wipe it out as a sponge erases a record from a slate. A thought is never secure until it has passed from the mind into the heart, and has become a desire, an aspiration, a passion. When the law of God is taken into the heart, it is no longer something merely remembered: it is something …

The Inward Laws
I will put My laws into their hearts, and in their minds will I write them. Their sins and iniquities will I remember no more.' (Hebrews x. 16, 17.) The beginnings of religion lie in the desire to have our sins forgiven, and to be enabled to avoid doing the wrong things again. It was so with David when, in the fifty-first Psalm, he not only cried, 'Have mercy upon me, O God, and blot out my transgressions', but 'Wash me, cleanse me from my sin'. Sin is a double evil. On the one hand, it creates …

"But a body Thou hast prepared Me."-- Heb. x. 5. The completion of the Old Testament did not finish the work that the Holy Spirit undertook for the whole Church. The Scripture may be the instrument whereby to act upon the consciousness of the sinner and to open his eyes to the beauty of the divine life, but it can not impart that life to the Church. Hence it is followed by another work of the Holy Spirit, viz., the preparation of the body of Christ. The well-known words of Psalm xl. 6, 7: "Sacrifice …
