First, making the font larger, or changing the colour, doesn't add strength to your argument.
Second, your statement is this, "Unbelievers cannot understand Scripture because they don't have the Holy Spirit" while the Scripture says, "The natural man does not accept the things of the Spirit of God, for they are foolishness to him, and he cannot understand them, because they are spiritually appraised."
Those two statements don't say the same thing. You're claiming that the Scripture "clearly says" one thing, but your assertion is not that one thing. Scripture does not state that "unbelievers can't understand Scripture." You're doing what many Christians mistakenly do: reinterpreting Scripture (paraphrasing) and then claiming that your paraphrase is a true representation of what the Scripture says. That's both arrogant and erroneous.

I also find your objection and argument very philosophical in nature and very moot - relevant to the thrust of the intended message.
