Is it a good idea for Christians to get involved in politics, because if they are involved in it, they tend to lie, make promises they can't fulfill and sometimes get their hands dirty which is sin.
Because of the untruthfulness involved in politics, Christians should be mindful of going into it. Christians can serve as guides or consultants and pilot the affairs of the nation from that angle. But politicians standing in to be voted for is wrong. Alot of lies are told during campaigns and after it to convince citizens. They may say it is harmless lies but that is not true. Every lie is harmful and it is a sin.
And ministers of the Gospel, are they suppose to endorse any candidate to their congregants. What's your take?
They can do that. They are leaders in their own field and have every right to their followers to lead them. But what will be wrong will be to stand at the altar while preaching is going on and say it. They can find a way to let their congregation know without broadcasting it.
