Passion

Great callings come with great passion. It was Jesus' compassion for the people that caused Him to do miracles. And the reality of heaven and hell should stir us to do something to reach the lost. We tend to suppress passion because we don't think God likes extremes, but truly He wants us either hot or cold, all the way in or all the way out, never lukewarm. It is the passionate, those who are on fire, who get things done for the kingdom of God.
