Wisdom, knowledge and humility are interrelated. You cannot have wisdom and not be humble. Knowledge teaches that pride leads to disgrace, and with humility comes wisdom(Proverbs 11:2).
We cannot claim to be wise, yet act unintelligently. The fruit we bear after acquiring knowledge and wisdom must reflect the love of God and our neighbour. You can't go wrong with humility, goodwill, love for one another, and goodness towards all men. Let your light so shine, that all men will know that you are a Christian by deeds not words. Mirror Christ anyway, anywhere, anytime, anyhow.
