In A Renegade's Guide to God, David Foster tells a story of a wealthy man who built a large art collection with his son. The son goes off to war and is killed. Later a soldier shows up at the man's door with a portrait that he had painted of the man's son, saying that the son had saved his life. The portrait is given an honored place in the man's art collection.
The wealthy man dies and his entire estate is put up for auction. The first item is the portrait of the son. The crowd is waiting for the "good stuff" i.e. the Picassos, Rembrandts, and other great works. No one bids on the portrait. Finally a man bids ten dollars. It is the one who painted it and ten dollars is all he has to give. Because no one else bids he is the highst bidder. The auctioneer then says that the auction is closed. There was a clause in the will that states that the son's portrait was to be the only thing auctioned and that whoever bought the picture would get the entire estate. So the soldier, who gave everything he had to get the son's picture, also got everything else.
That's what being a Christian is all about. You give up everything you have to "get the Son", and you get everything else that the Father has. It's all about a relationship with Jesus. It's not about a bunch of rules, how you dress, what kind of Bible you carry, how you vote, what kind of music you listen to, whether you smoke or drink, or any other external things. It's about whether you realize that you can not save yourself and that Jesus Christ loves you and has died for you so you don't have to die. It's about having a relationship of love with the Creator. It's about following Jesus and letting his Spirit guide you and form you into his image.
Jesus said he came to give us a life that is abundant and full. That's the way Christians should be. Are we?
