The cross is not simply part of our message to the world, but rightly understood it is the whole of it.
Be faithful in your calling. Shine as a light in the world. Do not let compromise eclipse courage. It is better to fail in a cause that will ultimately succeed, than to succeed in a cause that will ultimately fail.
Live in the light of Jesus, who died on a cross for us. God rules and in the end He will demonstrate His power and righteousness.
