“You’ll have to compromise your faith to be involved with politics.” That is a common reason given by believers [not to get into politics]. I have not found this to be the case. I belong to a major political party and served in elective office. Never was I required to do anything that was contrary to my faith. More than once I was on the short end of a vote (sometimes 99-1) and my stay in elective office wasn’t long, but I never had to compromise.
