Mathew 5:3

Blessed (spiritually prosperous, happy, to be admired) are the poor in spirit (those devoid of spiritual arrogance, those who regard themselves insignificant), for theirs is the kingdom of heaven (both now and forever). 

When we have a teachable spirit willing to learn, we can learn so much from God.  God has infinite wisdom to give us, but we also must be willing to receive the knowledge.  When we leave our own preconceived ideas behind and open ourselves up to God and His ways, we gain wisdom.  A humble spirit opens doors for us to grow.
