So bosk, is it a Christians responsibility to make sure other people are acting morally?
That is sort of a loaded, multifaceted question, as I understand it. Here is my multi-part answer:
It is definitely a Christian's responsibility to, as gently as possible, point out to those who are not acting morally that they are not acting morally. Beyond that, I do not believe it is a Christian's responsbility to "make sure" people are acting morally, and I do not believe it is a Christian's business to try, for the most part (excluding, for example, making sure your kids do right when you are raising them).
However, tying your question back to the question of the N.C. amendment and other anti-gay marriage laws, I do not see that as Christians "making sure others are acting morally." I could be dead wrong, but the way I see it, by putting it to a vote, the government is essentially asking everybody, Christian or not, what we think on the issue. Because we are given a voice on the subject, I think it is perfectly appropriate to vote on it as a Christian. And going back to my opinion on the subject, which I posted earlier in the thread, I do not believe the government should be about granting special privileged status to conduct that is not moral. Therefore, I believe voting on laws the clarify that "marriage" should not be extended to homosexual relationships is approriate. Again, I may be completely misunderstanding what the proper role of Christians in politics should be, but that's my take on it. And, as I also mentioned earlier in the thread, if it were legal in all 50 states tomorrow, okay. Others who also have the right to use their votes who hold a different opinion than I do would be in the majority, so so be it if that's the case.
