Very good points, twayneb.
While I don't mind listening to apologists who try to "defend the faith," the notion of "defending the faith" is odd. The faith doesn't necessarily NEED "defending." It is the "substance of things hoped for and the evidence of things not seen."
I will say this: There is a danger when believers who often almost gloat in their "ignorance" (as "unlearned men") attempt to "defend" or "proclaim" the faith through natural means. I once attended a session where a man was proclaiming the "truth" of the Word of God in regard to science. Yet, his presentation was riddled with half-truths, straw man arguments and even outright nonsense. He was relying upon "science" and "nature" for his defense of the faith...but lacked even rudimentary understanding of science and nature. As a result, some young people walked away puzzled.
Yes, I believe in the Biblical account of Creation. However, there is a danger in presenting it to the children of this world while using the very devices that they use unless we truly have mastered those devices. It is almost as silly as employing a translator for a mission trip who doesn't really fluently speak the language of those that we are going to minister to.
If we feel a need to "enter the fray" of the supposed wise men of this world with arguments, education and natural experiences, then we will simply debate. They will laugh at those who do not have an argument that makes sense to their sense of logic or education. Yet, if we present the Gospel as it is -- allowing God to do His own work (naturally or supernaturally) -- then we won't hinder through fleshly ways the spiritual work that God wants to do.
Unfortunately, those who claim to rely upon the "supernatural power of the Spirit" are often some of those who also try to argue positions based upon natural means. Moreover, they are often lacking the very power that they claim to rely upon. Consequently, the Gospel isn't proclaimed as it should be...and might even be hindered by the very "willing" vessels who boast such things.
