Imagine you find a chest full of gold coins! Wow! But imagine you're lost in a dark forest. Does the gold help you get out of there? No. Gold is heavy and doesn't talk. At that moment, what's worth more: the gold or a Map and someone smart to teach you the way? The Map!
The Bible says "speaking with knowledge" (knowing the right things, knowing how to pray, knowing how to say sorry) is the most precious jewel there is. Money gets spent and runs out. What we learn and say stays forever!
