However, there appears to be no principle against the practice of voting itself. For example, there is no reason why a board of directors should not take a vote in order to arrive at decisions affecting their corporation. Congregations of Jehovah’s Witnesses often make decisions about meeting times and the use of congregation funds by voting with a show of hands.

They respect and cooperate with the authorities who are duly elected in such elections. (Romans 13:1-7) As to whether they will personally vote for someone running in an election, each one of Jehovah’s Witnesses makes a decision based on his Bible-trained conscience and an understanding of his responsibility to God and to the State. (Matthew 22:21; 1 Peter 3:16) In making this personal decision, the Witnesses consider a number of factors.
