"My son, [reverently] fear the Lord and the king, and do not associate with those who are given to change [of allegiance, and are revolutionary],
For their calamity shall rise suddenly, and who knows the punishment and ruin which both [the Lord and the king] will bring upon [the rebellious]?"
-- The Words of God to Solomon, King of Israel, Proverbs 24:21-22 (Amplified Bible)
There is a time when fighting for "Change" will get you in trouble. It is when you are rebelling against the Lord and "the king." God has said here that their calamity will rise suddenly and suggests that the punishment will be severe. You would not want to be anywhere near this.
I know that we don't have person who we call "the king." That's because in a republic, the law of the land is the king. It is obvious that in the United States, the law of the land is our Constitution. To make this proverb clear to us we could say,
"Don't associate with people who disrepect God and the government by attacking the constitution in the name of change. Who knows what kind of trouble they will be in when suddently authorities come down on them."
Obviously, the "Fear of the Lord" is supreme. If you find yourself in a government that doesn't fear the God (The one of the Bible), then, clearly, this doesn't apply as God has made it clear that we should obey God rather than men. In other words, when the king is a rebel, the whole country is in trouble. We know that rebel leaders of the past have been brought down suddenly such as Hitler and the recently removed leader of Iraq.
Who are the authorities? Well, according to our constitution, "we, the people", are. We are not rebelling to uphold the constitution. In fact, the constitution says that it is our responsiblity to uphold it. Instead, it is our responsiblity.
