Excellent post. Add to C.S. Lewis - the works of Francis Schaeffer and, today, the work of Ravi Zacharias - and one can be well equipped - to explain to the modern mind the truth of the Gospel. Of course, underneath it all is the TRUE TRUTH of God and the fact that His Word is also TRUE TRUTH. Until one has experienced those truths, first hand - in their own lives - and the "author"'s presence Himself in their lives - one will still think there is a "debate". The debate is with us feeble human beings weighed down by our sins, our pride, our "self" isms. But the shining, unalterable truth of God's existance and His entrance into this world as a human being - Jesus Christ - God with us - and his reconciling of lost humanity through the shed blood of our Savior on that horrible cross - simply is not up for a "vote" or even a "debate" before the "vote". No vote gives us truth. NO "poll" decides whether or not there is a God and / our the reality of His Son as the lamb of God who takes away the sin of the world. It is either true or it is false.
Thanks be to God - IT IS TRUE! HE IS TRUE! Alleluia!
