Evangelical

What is an evangelical? Its probably one of the most misunderstood words in our generation... and it has come to be a hated word, and the fault is partly our own. For many evangelical means a commitment to a political party, means anti-abortion, anti-gay, anti-climate change, anti-immigrant, etc. We are known for what we are against rather than for what we are for. Biblically speaking what actually is an evangelical? How should evangelicals live?
