ABSTRACT
One of the key secondary ideas in C. S. Lewis's Mere Christianity is the distinction between the biblical Greek words Bios and Zoe. Lewis proposes that in our natural condition, human beings have a self-centered biological life, but not necessarily a developed connection to the spiritual world. The distinction between Bio and Zoe is the distinction between the lives that humans have and the life that God has. Lewis returns frequently to the relationship between morality and theology. Lewis believes that Christian morality is a process of inner transformation that depends on every choice a person makes. He argues against the type of morality that sees God as the cosmic lawgiver, rewarding good deeds and punishing bad deeds. For Lewis, the spiritual life is elevating. Much of what makes Mere Christianity such a significant work is the way Lewis incorporates so much of his academic learning into his apologetics.
