Now that I've voted, I have to break some news to you modern-day Christians. Democracy, on itself, is an anti-theistic system. It is a political system where the masses are believed to be soveriegn and have authoritative powers to decide the nation's governance. It disregards the soveriegnty of possible deities or gods where the ruling power rests solely on the people.
So, if you, a christian, cast a vote in an election, you have to ask yourself, are you sacrilegious in your exercise of democracy? Because the moment you put down a vote in political elections, you assumed sovereignty for yourself and not to God. Basically, you are doing what's right in your own eyes, deciding what's good or bad for yourself. (In those days there was no king in Israel: every man did that which was right in his own eyes. -- Judges 21:25 KJV)
This is the reason why Islamic nations/states generally opposes democracy as their political system and use Islamic principle as their code of governance. Because muslim leaders, in general, believe that sovereignty belongs only to Allah/God and they will object any attempt in shifting ruling power to the people.
Of course, christians and muslims are different in our beliefs. But then does it mean we are entrusted by God to hold such authority? In a parliamentary democracy, the code states that the parliamentary sovereignty is absolute and above all institutions. So, where is God in this system of governance?
It's a big ask to get you christians to come up with a resolution without compartmentalising secular politics with spiritual practice. But note, God is bringing us the kingdom of heaven, which is a political system, isn't it? So do you believe in absolute monarchy, where God is the only sovereign entity? Or do you believe in a separation of powers between Church and state? If it's the former, why did you participate in democracy? If it's the latter, how would you justify?
