If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you. James 1:5

There is no shame in admitting that we lack wisdom, especially to God. After all the wisest king ever lived - King Solomon - even he asked God for wisdom. 

Therefore give Your servant an understanding heart to judge Your people and to discern between good and evil. For who is able to govern this great people of Yours?" 1 Kings 3:9

My favorite King David too acknowledged the wisdom he received from God Almighty:

Surely You desire truth in the inmost being; You teach me wisdom in the inmost place. Psalm 51:6

Prophet Daniel too confirms wisdom comes from the Lord:

He changes the times and seasons; He removes kings and establishes them. He gives wisdom to the wise and knowledge to the discerning. Daniel 2:21

Matthew affirms that if we ask, it will be given:

Ask, and it will be given to you; seek, and you will find; knock, and the door will be opened to you. Matthew 7:7

Now is there any reason not to ask for wisdom for ourselves?
