Then maybe stop eating because food is "part of this world".
Taking our que from Jesus and the apostles, it is not difficult to draw appropriate lines and not cross them.
Did Jesus eat? Whilst walking through a field on one occasion, Jesus and his companions grasped a handful of grain and ate it on the move. It was a Sabbath and the Pharisees accused them of harvesting. Was the son of God breaking the Sabbath? Was the law meant to be taken so rigidly? The legal eagles apparently thought so.
So eating is OK by Jesus' own example. A balanced approach is needed. Many of the Israelites were farmers, so growing food is OK, cooking it is too. Jesus cooked breakfast for his apostles.
There is nothing intrinsically wrong with politics, and all religious bodies, including yours, have a political aspect to them because decisions have to be made by someone.
In speaking of the world and its ruler we can see what Jesus meant when speaking of the rulers of this world. (1 John 5:19; 2 Corinthians 4:3-4) Having an organised body to take the lead and accept responsibility for its actions is important in any organisation, no matter how big...or small. How the peace and stability of that organisation is maintained is largely about how roles and duties are performed and the correct attitude demonstrated towards others. Jesus said "all are brothers" which means no 'bosses'. (Matthew 22:8-9; Phillipians 2:2-4)
What is "intrinsically wrong" with politics is the well known fact of human nature that "power corrupts"...we all know it does, so in any political or religious organisation, there needs to be oversight, but not power. The buck has to stop with someone, and in Israel, there was order and duty, but the head of their nation was God, represented by those he appointed. All answered to him. It was God's rules that had to be followed, but as the Pharisees demonstrated, for every law, they made many, virtually impossible rules. No wonder the sheep got lost.
Also, we see God actually setting up political leadership at times, such as with David, so if "be not of this world" is incumbent on politics, then why did God violate his own supposed teachings?
Having a human king in Israel was not God's idea. It was the people who wanted a human king to make them like the nations. God warned them about the downside of this arrangement, but the people would not listen. (as usual) So Jehovah instituted human kings (only from Judah) and allowed the people to again experience the full consequences of their ill conceived decision. How many wicked kings led their nation astray, warranting often severe punishment from God? Please think about that.
IMO, what Jesus was teaching was not to avoid politics, which is virtually impossible anyway, but for the purpose of setting priorities.
Again, what example did Jesus and his apostles set in this regard? Did they ever advocate entering the Roman political scene in order to lift the oppressive yoke of pagan political domination? The Jewish zealots were constantly plotting against Rome, but there were none of Jesus' disciples among them. Not once do we see Jesus advocating political involvement.
When speaking about the political powers of this world, we never see Jesus saying that politics would solve any of their problems.....in fact, it was the political powers and the people who supported them that were opposing the work that Jesus and his disciples were doing. They advocated God's kingdom as the only hope for mankind. And the worldly kingdoms were going to be "crushed" out of existence when the judge comes for his accounting. (Daniel 2:44) We cannot be found supporting this world's rulers when they don't follow Christ's teachings. In spite of some claiming to be "Christians", they have so much blood on their hands. (Isaiah 1:15)
If all "righteous" people never get involved in politics, doesn't that leave all leadership, including with your JW's, to the "unrighteous"?
Just because the governments of this world control our lives to a relative degree, we still have to live in this world and God sees to it that his will can be done in spite of it. If we involve ourselves in politics, conflict will divide our loyalties. If we are part of the problem, we can never be part of the solution.
The "unrighteousness" are not necessarily "bad" people but simply not believers, which means that their behavior and agenda is not governed by God's laws....they can make their own. Many "good" humanitarians are atheists. God never said that being a "good" person was all that was needed.
When we consider what God has required of human beings from day one...."obedience" to his commands....then it becomes obvious where the line of demarcation begins and ends. We must be good, but we must also be obedient to God from the heart. He must be our Sovereign ruler.
Christians are not to be either "pro" or "anti" politics....we are to be completely neutral....i.e. we are to obey the laws of the land so that none of us suffer as a criminal (a thief or a murderer etc) but we also cannot break God's law if our government asks us to....i.e. to kill another human being just because they are of a different nation, religion or political persuasion. Christians are to love their brothers as well as their enemies.....a command to go to war and kill those who fall under those categories divides our loyalties and separates us from God.
We cannot serve two masters. Those who want to be citizens of God's kingdom cannot pledge allegiance to any worldly nation. We are to pledge our alliegance to God alone. Where there is a conflict of interest, then there is only one choice for Christians. This is how we view things.
