God gave us a new song of praise. Must we climb onto a bandwagon to sing it? Bandwagon Christians fear individuality because evangelicalism condemns free thinking, even outside our creedal boundaries. Just try wearing spiked, brightly colored hair, tattoos, and body piercing to most evangelical churches(no, looking weird isn't necessarily free thinking). Though the Bible has nothing to say about style outside of looking like a whore and cross-dressing, you will be shunned.
Legalism is carnality, and God will judge it as such.
