This has nothing to do with the ordinary IQ. One who has high IQ (ordinary) usually becomes highly educated and knowledgeable, possesses a lot of self-confidence, and is proud of what s/he can accomplish. Unfortunately, this intelligence often gets in the way of finding God because it can blind the person from seeing that it is impossible for a creature to be greater than the creator and that all intelligence comes from God. Basically, the more one thinks highly of himself, the more he becomes a nobody before God. The one who has high spiritual IQ is the one who remains humble and becomes somebody in the eyes of God. All this brings us to what Jesus had said, "Whoever exalts himself shall be humbled, but whoever humbles himself shall be exalted."
