There's two kind of the drivers, the ones that overtake a slow vehicles on the highway and those that patiently follow the slow drivers. Within Christianity we also see a distinction between those who 'make' God's will happen and those who patiently wait for God's will to come to fruition. Now, I'm not saying we should all sit at home on the couch waiting for things to 'happen' in our lives, but rather inviting us all to rest in God through the delays and the obstacles in our lives, while remaining faithful to what God placed on our hearts to do.
