That depends on one's definition of good. Ultimately striving towards the types of behavior that Jesus demonstrated is an ideal and not one that will ever be achieved. We all have failings and the world we have is the world we have. Whether it could be better or worse, I am not going to worry about that, as I can try to put what good in the world I can, but ultimately, its not up to any of us. I am going to worry about my behavior, my relationships with people, the type of attitude I show people, being a good friend, being charitable, being loving, being peaceful, I will dare to show love where others are afraid to, I will be kind when the world says that is stupid and I will just get taken advantage of. In all of this I will be strong because I have a hell of a partner in my moral, spiritual, and mental growth to become better every day. I have my comfort to turn to when things suck. I have someone to pray to when I want to express my hopes for myself, others, or the world, but also will accept the decisions that God makes.
That, to me, is Christianity. Its not about forcing others to my boot or societal control. Its about what love, examples, and good can I put in the world as my partner in this, (who is far smarter than I will ever be) helps me make those good choices that reveal that good in either the human soul or God.
