A lot of us have watched movies about spies (also known as undercover agents). A spy is a person employed by a government or other organization to secretly obtain information on an enemy or competitor. So they have their mission and in order to carry it out, they take on an identity which they live out such that nobody they relate with knows they are spies. They blend in with other people, working a normal job, with a family….on the outside, your everyday folks but in reality, something else.
It occurred to me one day that we are like undercover agents. We belong to families, go through the different phases of life here on Earth, perhaps marry and perhaps have children, get jobs or run businesses, etc. but underneath it all, we are on a mission. All the things I just enumerated are done as we blend in because we are IN the world but it behoves us to keep our focus on our mission and not get caught up with these things because we are not OF the world.
