Sadly, some Christians do not make it a habit or custom to regularly worship God together with other Christians. For various reasons (a majority of them sinful!) some Christians simply skip corporate worship Lord’s Day after Lord’s Day. Scripture is clear, however: God’s people must regularly worship him with others! Hebrews 10:25 talks about “not forsaking our own assembling together, as is the habit of some” (NASB). Below is William Lane’s helpful commentary on this verse in Hebrews – and notice the seriousness of regularly avoiding public worship.
The failure of the writer [of Hebrews] to specify why some members of the community had stopped taking an active part in the meetings of the house church has invited a wide range of conjectures. The reference to ‘custom’ or ‘habit’ …implies a situation of indifference and apathy, which is consistent with other indications throughout the sermon (2:1-3; 3:7-15; 4:1; 5:11-14; 10:23). …It is sobering to discover that in the early second century in Rome it was simply preoccupation with business affairs that accounted for the neglect of the meetings of a house church (Herm. Sim. 8.8.1; 9.20.1).
Whatever the motivation, the writer regarded the desertion of the communal meetings as utterly serious. It threatened the corporate life of the congregation and almost certainly was a prelude to apostasy on the part of those who were separating themselves from the assembly. The neglect of worship and fellowship was symptomatic of a catastrophic failure to appreciate the significance of Christ’s priestly ministry and the access to God it provided.
The reason the meetings of the assembly are not to be neglected is that they provide a communal setting where mutual encouragement and admonition may occur…. The verb parakalein includes the notions of warning and reproof as well as encouragement, with the implication that reproof should be given in a loving way. The entire community must assume responsibility to watch that no one grows weary or becomes apostate. This is possible only when Christians continue to exercise care for one another personally.
