I cor 2:14 is about lost people not carnal. Just because Paul does speak about carnal believers does not in any way make verse 14 about carnal believers. The people spoken of in verse 14 are the "natural man" It says they he can't understand. The carnal believer can but doesn't. Paul is peaking to believers in chapter 2 and he makes a point that its the Spirit that helps us understand. The natural man cannot understand because he doesn't have the Spirit. Paul does speak about carnal believers, and he says that he couldn't address them as spiritual but as carnal. These carnal believers were acting like the unbelievers in verse 14.

The Bible is very clear than men are born depraved. No man can come unless drawn(John 6). Now, we can debate if all are drawn or not, but the point still remains that the natural man cannot come to Christ without the Spirit.
1. No excuse Romans 1:20If the lost can't even understand the gospel then you have just given them the perfect excuse for not believing it.
