David Limbaugh (Rush’s bro) has a brand new book out – Jesus on Trial. This is a well written and compelling work defending the truth of the Gospel. Sean Hannity recently talked with David about the book. PJTV also has an interview.
David recounts when Steve Springer witnessed to him:
Steve did not fit my perception at the time of the stereotypical young Christian – a judgmental holy roller who accepted Christianity uncritically. He exhibited an extraordinary measure of grace. He not only didn’t take offense at my skepticism, but he patiently retrieved his Bible … and began to walk me through a few fascinating verses. 
Josh McDowell, Ravi Zacharias and Paul Little were instrumental in leading David to Christ. David says this about philosophy: “I believe philosophy can be a worthy field of study, but I don’t think we can improve on the Bible’s revealed truths in conveying God’s nature and His plan of redemption and salvation for mankind.” 
After David had read the Gospel of John several times, he confesses: “… I was on fire and began reading the Bible and everything about the Bible and theology I could get my hands on.” 
David references Ray Comfort in a positive light in his chapter “Science Makes the Case – for Christianity.” Comfort apparently favors Young Earth Science (YES).
David references Kurt Wise’s Faith, Form and Time which defends YES. David also quotes Nancy Pearcey who apparently affirms the young earth. Pearcey was a contributing editor to Bible-Science News for a number of years. This was published by the Bible-Science Association (founded by Walter Lang) whose motto included “A Young Earth.”
David points out that a large number of Christians,
… believe in a young earth, and of those who do, many are hardly science deniers; they don’t base their beliefs simply on blind faith. They subscribe to different scientific theories, even if one might find those outside the mainstream of scientific consensus, or they question the unprovable assumptions used in dating techniques … 
Where is the wise person? Where is the teacher of the law? Where is the philosopher of this age? Has not God made foolish the wisdom of the world? For since in the wisdom of God the world through its wisdom did not know him, God was pleased through the foolishness of what was preached to save those who believe. Jews demand signs and Greeks look for wisdom, but we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles, but to those whom God has called, both Jews and Greeks, Christ the power of God and the wisdom of God. (1 Cor. 1:20-24)
