When Jesus says in the Fourth Gospel, "I am the way, the truth, and the life," does he mean that Christianity is the only true religion, or did he mean something else? As we know, Jesus did not found a new religion nor did he pave a new way to salvation or truth. Rather, Jesus worked for God, by showing the way of God, testifying to the truth, and engaging in the work of liberation. Jesus in the Fourth Gospel, like Moses, is sent by God to liberate people from darkness. Unlike today's triumphant Christianity, the Johannine community was a small, marginalized, expelled community that struggled because of their faith. It will be very interesting to see how this struggling community was transformed into a loving community, following the model of Jesus.
I wrote this book out of my hope that the Fourth Gospel and John 14:6, in particular, could be the scripture of engagement, embodiment, and empowerment for Christian readers. I hope this book will help the reader rethink the role of the Logos or the "I am" sayings in the Fourth Gospel. In a pluralistic society, the focus of the gospel shifts from conversion or theological doctrine to the empowerment of people. I dream that this book will contribute to theological education in that the "I am" sayings of the Fourth Gospel give a voice to inclusivism rather than exclusivism, solidarity rather than marginalization, and liberation rather than oppression. In the pluralistic life contexts of America today, the theology that accepts others as friends is very important; it engages others on the basis of God's love and justice. With a focus on the language of embodiment and empowerment, theological education can be more inclusive to others and help students reorient their attention to the present life in the world.

So much so their understanding of faith and salvation is very limited. It may be summarized as follows:
