In the 1st century, Christians found themselves living as a subversion to the powers and politics of the kingdom around them. They saw themselves as bringing in a new Kingdom, one that has existed since the beginning of time, but was crashing into this world, bringing hope, light, and True peace. They preached the Good News of Jesus Christ, which in the 1st century, had some very steep implications. It meant that they were opposing Caesar. They had a different King.
In the 21st century, Christians have chose live with and within the powers and politics of the kingdoms around them. Christians now travel, not carrying the Good News of Christ, but preaching the good news of Caesar (now namely Obama or McCain). We are trading the Hope of True hope, light, and peace for the empty hope that can be found in politics or a politician.
May God's Kingdom, not man's, truly come.
