What does this verse in the Bible mean?

To me, it means that God's Word-every commandment, every nugget of knowledge and wisdom, every testimony of how God worked in people's lives that are in the Bible, are all more desirable than pure gold and of much more value. Everything that we need to know about how to live, how to be acceptable to Him, how to be like Him (holy), how to have eternal life, and how to handle all of life's adversities are contained in His Word. His knowledge and His love for us to share His knowledge and wisdom with us is worth far more than to us than obtaining the very best material things life has to offer. His Word warns us what natural consequences we will suffer if we don't take His advice. If we keep (follow) His wisdom, there is great reward (we have a more blessed life, we don't suffer the natural consequences that come as a result of wrong action on our parts, we can gain eternal life by accepting His Word of how Jesus paid the price for the natural consequence of sin (eternal damnation in Hell) so that we can enjoy the reward of eternal life in Heaven with Him even though we do not deserve it (because we ALL are naturally born as sinful creatures). That's what a lot of people do not understand...God doesn't "send" anyone to Hell. He doesn't want anyone to go there. It is the consequence for remaining a sinful creature so He made a way that we don't have to suffer that consequence.
