Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching. (Hebrews 10:25)
To wildly sling a verse taken out of context all over the place does nothing to promote truth and godliness; instead, it damages the faith and the lives of those who respect the Bible and try to obey it.
Much harm has been done by the misuse of Hebrews 10:25. It has been used, often without regard to the context of the verse or the situation of the audience, to demand church membership and church attendance, and to threaten those who abstain or withdraw.
But the reason for withdrawal is paramount in this verse; in fact, unless our understanding of the verse is thoroughly colored by it, we would miss the point of the verse, and indeed the point of all of Hebrews. The reason for withdrawal is so essential that it cannot be applied without this context.
Because its true meaning has been obscured, the verese has been used by church leaders to threaten believers into submission without having to improve their own ministries or to allow people to follow Christ when their leaders have failed.
