The act of having to stop and do it. It may be that we're quarreling over nothing, because I agree we are to pray constantly and be soberly on-alert.
...was our revolting against Great Britain a Christian act?
That's rather the ultimate test case, isn't it? First, using the framework I've advocated, not unless continuing to remain British would break God's deeper laws, and many Tories didn't think so and remained loyal to Britain. The majority of colonists maintained it would, and they were careful to make exactly that case in their Declaration of Independence.
They began by citing as self-evident truth their unalienable rights, with which they were endowed by their creator. Then they demonstrated that Britain's rule had become destructive of those rights, thus giving them the Right and even "the duty" to throw off Britain's rule. After citing a long list of abuses they chronicled their efforts to work within the system, without success. Having made every legitimate effort to remain loyal, they came finally to "acquiesce in the necessity" of rebelling.
Perhaps one could argue the merits of their argument, but the fact is they structured it as I've outlined: obey unless God clearly calls to you not to. Therefore, I have every confidence that they were acting in that situation as God would have them do. It is interesting, I think, to note that there has never been much if any reconsideration of their basic position--that is, few if any have said they were wrong in their approach. Could they have endured longer? Beside the point--they endured plenty and made a handsome case for putting up with no more.
In your opinion, would that situation be substantially different if they had lost? Thankfully, we will never know for sure, but your post illustrates one critical point. While God's will and His truth are perfect and absolute, our understanding of them is much less so. Then, as now, christian men of good faith disagreed over the affairs and foibles of men, both sides convinced that they were being true to His word.
I see non Scriptural citations in the Declaration for either the claim that liberty is a God-given unalienable right or the claim that a ruler can justly be thrown off if he becomes destructive of that right. What Scripture do you believe supports those claims?
