I've heard it said that Christians should be in the world, but not of the world. We aren't supposed to be chasing the temporary 'stuff of earth', because this earth is not our home. Our eyes should continue to focus heavenward. However, we aren't supposed to be hiding our light within us from the world because we still live in the world. We are in a war and it's good vrs evil. "For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms." Ephesians 6:12
Adventure is fighting against evil for righteousness. Adventure is sharing your faith with those around you. Adventure is saying "Lord, I'm here, use me for your glory."
And I suppose that's why I love adventure so much. Giving up yourself for a greater cause no matter what personal cost thrills me to the core.
