When I wrote that I thought to myself, He wont bring up Pentecost, will he?
In case you missed the details of the story, the men heard the Word preached in their own, known languages (Acts 2:6,11). They were not speaking heavenly gibberish.
It is not the power of the preacher or even the eloquence of the message that will bring a skeptic to understanding, but the power of God's word and the moving of the Holy Spirit.
You act as if Henry Morris, by contending for the truth of the flood, is somehow going to be responsible for some skeptic going to hell because he didn't believe Henry Morris. Well that ain't gonna happen. If that skeptic wants to use Henry Morris as an excuse for not believing the Bible, then that skeptic will have nobody but himself to blame when he stands before God on Judgment day.
Personally while I am open to just about any interpretation of the creation, I tend to believe that since the creation was a miracle and since God affirmed in Exodus Chapter 20 that he created the heavens and the earth in six days, that, in fact, God created the heavens and earth and all that in them is in 6 days.
You got a problem with that?
