"Wisdom is the most important thing, so get Wisdom!" - Proverbs 4:7
Young kids ask "Why? Why? Why?", "Why, Why, Why?" and then deconstruct and reconstruct their toys and the stereo. Mature adults say, "Because!" and instruct instead "Don't touch buttons!" Why would Jesus say we need to be like children to enter the Kingdom of God? Don't we adults have the wisdom?
Scripture: Proverbs 16:16
"Wisdom is worth much more than gold. Understanding is worth much more than silver."
