Are We ambitious for the Gospel????

I have been reflecting upon ambition or in better words being driven. As tent-makers we are called to run a business. We are very ambitious in business going after contracts and students. We hold ourselves to standards of quality and service. If we do not do well we do not eat, at least as well as we would like. Do I have this same urgency, ambitious, drive, for the Kingdom of God? Recently I have been chanting to myself the old high school cheer, "Be Aggressive, B-E- Aggressive." It is my hope to be more aggressive for God's Kingdom.
