As Christians, we can spend a lifetime accumulating information and yet never have any wisdom. The problem with God's wisdom is that it is so simple, few can understand it.
Take salvation, for example. The way to receive salvation from God is so simple that anyone who wants to can understand it. Nevertheless, millions upon millions don't understand it. What's up with that!
An intimate relationship with Christ can only come from spending time in His Word, listening to Him and being in His presence often. So then it might be that understanding salvation, for instance, might require us to spend time with salvation, listening to salvation's message and coming to the presence of salvation often. (How many Christians know how to do those things?)
