There is a lot of arguing over whether or not a Christian should participate in Halloween. My opinion is that it depends on the condition of your heart. If you have Jesus in your heart then Halloween is just a fun time to put on a costume and eat candy regardless of what it means to pagans. Likewise if you don't have Jesus in your heart Christmas is just a time to put up a tree and exchange gifts regardless of the fact that to Christians it is the celebration of the birth if our Lord. So chill out, put on your costume and eat your candy. Simply doing so is not worshiping the devil.
