"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.

A famous athiest question posed to believers is:

"Could God make a rock so big that he can't move it?"

This is an attempt to put the believer in a logic trap.  If the believer says "Yes", the response is then that makes God to no longer be omnipotent (all powerful) because he would have made a rock he can't overpower.  If the believer says "No", then the response is that God must not be omnipotent if he can't do this.

I want to start this by changing the question to what I believe is really being asked:

"Could God give up his omnipotence?"

I would answer: "Yes."  God could choose to stop being God.  The real question is:

"Would God give up his omnipotence?"

To this I answer: "No."  This is easy because God stays the same.  The logic problem that the athiest is overlooking is that just because a person can do something, doesn't mean that they will do it.  So, the real way to answer the "Unmovable Rock" question is to answer "Yes, but why in the world do you think He would want to do that?"  I would point out that we shouldn't assume that just because God can do anything that He would do anything.  That assumption is nothing short of absurd!  Omipotence is a description of the power that God has, it it does not describe his will.  To find out more about God's will, you can read the bible.  It is His will by which He demonstrates His great love for us.  We were sinners and it was within his power to destroy us, but He gave up his Son to great suffering take our punishment, even the punisment for an athiest.
