Christianity - Living in total sacrifice to Christ because of the sacrifice he made on the cross.
Not Christianity - Doin' it for the benefits.
I will agree, it is sad that the "christian church" has been labeled as a bunch of judgmental religious people who believe out of guilt.
Jesus' intentions were never to "guilt" people into belief, it is a realization of what we truly are as human beings after sin - disgusting in God's sight, and that it is only through the death and resurrection of Jesus Christ, that we may be found blameless after we die, and while we are alive. And, in that realization, further realizing that God (Creator) does not have to do anything for us (creation), because we are sinful, yet He still did, and does, and in that we respond with a life that is sold out for Christ.
Also realizing the amount of love for his creation, by sending his son, and choosing to respond in a way that would glorify Him through our actions and attitudes.
