Jesus calls on us to empty ourselves of pride, embrace humility and concede our weakness, for one cannot hope to pass through the narrow gate to the Kingdom of God without doing so.

Presuming upon our own abilities and not relying on Jesus to gain the Kingdom of Heaven will inevitably lead to despair and disappointment. The narrow gate is a reminder that the path to Heaven is a difficult one that can only be trodden through complete reliance on the Son of God.
Pride has been the downfall of many, including Satan and the fallen angels. The saints, in their tenacious struggle for virtue, are apt examples of humility, the ablest weapon against pride.
In Christian tradition, pride is a more fundamental sin than the other capital sins, and thus is described as the queen, mother and principle of all other vices and sins.
