I think about God, I talk about God.

Always I'm wondering, is there a God?

But, some counsel me, all your thoughts and talks about God are

in vain, because, they say, God cannot be known by reason.

God can be known only by faith.

So, now I wonder, what is faith?

I imagine descriptions of faith an inner conviction that the

deepest truth, the reality of God, escapes reason,

an absolute certainty that specific religious doctrines

are absolutely true.

But, describing faith is one thing.

Having faith, quite another.

How could faith work?

I'm Robert Lawrence Kuhn, and Closer to Truth is my

journey to find out.

I start to study faith, then worry, is studying faith

self-contradictory, an oxymoron?

I find in the New Testament, the Book of Hebrews,

a definition of faith.

Now, faith is the assurance of things hoped for, the conviction

of things not seen.

Simply put, the biblical definition of faith is trusting

in that which you cannot prove.

But, how can such faith be actionable, practical, workable?

Would I want to have such faith?

Honestly, I'm not sure.

But, I do need to understand such faith, this I am sure.

I trained as a scientist, and I think as a scientist, and the

way of thinking of science seems to be the polar opposite of the

way of thinking of faith.

So, I begin with a man of science who became a man of

faith, Alister McGrath with a doctorate in Biophysics is

now professor of Science and Religion at

the University of Oxford, and President of the Oxford Center

for Christian Apologetics.

Alister, I want to know whether God exists.

Some friends tell me that I'll never find answers with a

rational approach, that I must have faith, and without faith,

I will go nowhere.
