To me a Christian is a person, with flaws and inadequecies just like everyone else. A Christian is a person who believes and follows the teachings of Jesus Christ. One who not only reads, understands and follows those teachings, but who incorporates them into their daily lives. One who can literally turn the other cheek, and not gain satisfaction over the misfortune of others. One who follows the Commandments and takes them to heart. One who follows the greatest commandment of all, "love your neighbor as yourself".
Funny, many Christian I know can spout scripture, and are quick to criticize the "unChristian" like behavior of others, but do not see it in themselves. A Christian, as well as other people of other religions, should practice what they preach.
Being Christian does not make anyone better than anyone else. Does not mean that you have preference in Heaven IMHO...a bad Christian does not have rights over a good non Christian.
By the way...I am Roman Catholic, and I definitely have to work at some of the above, but atleast I know I have to do so...
God, in my opinion made this world and everything on it. The birds, the flowers, trees, everything else and man. He loves all the creatures of this world, and I do not think that if a person leads a good life, he would punish them for not believing in him.
