In Matthew it says, "You are the light of the world. A city set on a hill cannot be hidden; nor does anyone light a lamp and put it under a basket, but on the lamp stand, and it gives light to all who are in the house” Matt 5:14-15 (NASU).
We as Christians need to look at ourselves the same way. God uses us to reflect Himself into the lives of those around us. Are you willing to be one of his reflectors?
