I view the world as a place that God gave us to worship Him. As a reward for worshiping Him, we are given the gift of Heaven which is a greater gift than we could ever imagine. As Christians, we should all try to get others to worship Him while on this earth so they can receive the reward of Heaven and worship Him there.
As a Christian, I am unique in many different ways. The one way that stands out the most to me is how I do everything for God. Whether I am playing sports or anything else, I am always doing it for God. If we all did everything for God, we would all receive the reward that is Heaven, but not everyone is given the oppurtunity to know who God is. So I am also different because I am able to teach those that don't know about God to teach them about Him so they can do it all for God as well.
