Initially it is a subjective thing(1 Cor. 2:10-"But God has revealed them to us through his Spirit.") It doesn't hit everybody b/c not everybody is spiritual(on the Damascus road, it hit Paul and Paul only.)
However, look at verse 12-"Now we have received, not the spirit of the world, but the spirit who is from God, that we might know the things that have been freely given to us by God." Once God provides the revelation, he will provide what is necessary to show it(in the event that it hasn't already been given). Here's the thing: to understand God one must come from a spiritual direction; if one comes from a physical direction in search of God, then one is searching in vain and will never find Him. If one does this, then one is putting the cart before the horse.
"For what man knows the things of a man except the spirit of man which is in him? Even so no one can the things of God except the Spirit of God?"-1 Cor. 2:11.
