Your Biblical Duty to Vote
As responsible citizens, Christians must strive to honour God in all areas of life (Matthew 5:14-20). We are to oppose evil (Isaiah 59) and work for righteousness. Christians therefore have a Biblical duty to vote.
“Select capable men from all the people - men who fear God; trustworthy men who hate dishonest gain - and appoint them as officials...”
Does your one vote really count?
When you do not vote, by default you cast your vote against the person or proposal you would prefer. When you do not vote, that vote is one less the opposition has to overcome, thus your "no vote" is a vote for anti-Christian policies.
