Did you know that the milk of God's word teaches the believer how to judge? Typically, I find that those who believe Christian's are not supposed to judge also believe that they are not to be involved in politics either. It is immature. If you have a problem with what I just said, then I strongly urge to go back to the Hebrews 6 Foundations workbook and do the lesson on The Eternal Judgement and you'll find a thorough study on the topic where you will discover that 1 Corinthians 2:15 says, "But he who is spiritual judges all things, yet he himself is rightly judged by no one." Christ calls us to judge things such as, words and actions. This is done by comparing the word or action to God's word.
Politics Verses Government
Did you know that the term politics cannot be found in the New King James Bible? Politics is not there. But you will find government all through the scripture. What do you think God was doing with Moses when He established the nation? What do you think a "kingdom" is all about? Why we can find reference to government in some fashion or form in almost every book in the Bible. From King Saul's interaction with the prophet Samuel, to Elijah's confrontation of the prophets of Baal led by Jezebel and allowed by King Ahab, to John the Baptist confronting social issues while calling out King Herod and Herodias' elicit relationship to Paul dealing with Elymas the sorcerer in front of the Proconsul, there are numerous examples of God desiring His people to engage, be involved in and confront civil government.
