Politics may be an art....but it is not art
.
I agree with you here. I have been saying the EXACT same thing.
Politics itself is not sinful. Christians should be concerned with the "politics" of the Church (of the community of Christians and the assembly). Church discipline would fall into this category. So would ministering to the needs of the congregation.
And yes, Satan uses Christian's desire for Church politics - for a righteous governance in the Kingdom of God - for world politics. Christians remove themselves from the proper affairs to concentrate on making a world which is already condemned appear less so evil.
To your point, world politics is perhaps the greatest evil Satan has used to deceive otherwise faithful Christians. Satan has used politics in America to compromise the Church, to strengthen his hold on the hearts of men, to weaken Christianity, and to undermine the gospel of Jesus Christ.
