Reading this, I am not exactly sure where you decided to come down on an issue, as it doesn’t appear that you actually stated an application from your commentary.
If you are stating that you can’t see having a woman leading the country based on your being a Christian, then I will say that would depend on how you interpret your Bible.
Israel was a Theocracy, and had a governmental system dictated by God, and therefore can’t be directly compared to any other country or government on earth. Israel stands alone in this regard as God’s chosen people.
Would we be better off running our government on Israel’s model? I don’t have an answer to that question, but I don’t believe we must as Christians expect our government to reflect Israel’s Biblical standards or abstain from participating in it.
I find in the New Testament many admonitions about a woman’s role of leadership in the church, in the body of Christ, but I think stretching these verses to apply to secular government is exactly that, a stretch.
You are welcome to hold your own opinion on the matter, but I have no trouble with McCain’s VP choice.
