I know there are those who reject anything to do with religion, seeing it as only the fire and brimstone rigid type. Yet, there is another lens if viewed through the teachings of Jesus in Matthew 25. A certain politician in Texas uses this as the basis for his actions and it does provide a much more positive view of the purpose of human life. That said, Luke exemplifies very well the type of life advocated in that passage of the bible: he reaches out to Matt, Levi and Julie in this time of need with compassion and selflessness.
Again, very powerful writing!
