You are looking at Christ 's actions when He came to save the world. Start looking at His actions when He returns and you will see His ruling of the world is the true politics. Foreign policy will be done a little differently. Instead of trade embargoes, He will withhold the rain which, is way more effective.
Zechariah 14:17
And it shall be that whichever of the families of the earth do not come up to Jerusalem to worship the King, the Lord of hosts, on them there will be no rain.
We live in a fallen world, corruption is everywhere. If one is going to withdraw on the basis of something being corrupt in places, we will not be involved in anything. The whole point of my statement is to get in there to prevent the corruption overtaking the system and controlling it without any checks or balances. Why my statement should boggle your mind boggles mine. Should we (Christians) stand against nothing and let the corruption take over?
I'm in my Father's business which is one of redemption and reconciliation, not "eek, I don't want to get my hands dirty".
You go your way and I'll go mine.
ps. In my country, our politicians are called ministers. Our chief, equivalent to your President, is called the
Prime Minister.
pps. It might also be worthwhile understanding what I mean when I use the word "politics".
