Apparently, there's "nothing new under the sun."
This is what Solomon found out. He said so in Ecclesiastes (1:9).
"...and I partly believe it." (1 Corinthians 11:18)
Contrast this with what Jesus says in the Gospel of Matthew (13:52): "Therefore every scribe which is instructed unto the kingdom of Heaven is like an householder, which brings forth out of his treasure things new and old". I would like to think that—while there might be nothing new under the sun—the "new" stuff, the stuff that Jesus is referring to, is over the sun. Above the sun.
Anything that is truth, is still truth whenever it's spoken. The truthness of the concept, precept, whatever, is true--just as true now as it was say, back in the Old Testament. When something becomes cliched or stale, it has nothing to do with the content of the information in question, but of the receptivity of the hearer. Take for instance, that old adage, "you can't judge a book by its cover"...maybe that's not a good example because publishers want you to do just that. Look at the cover of any Fantasy or Romance novel and you'll see what I mean.
Think of any cliched and powerless phrase that you hear nowadays. Anything from "Hi, how are you?/Fine thanks", to "breaking the bank", to "keeping up with joneses" to a dozen others on the tip of my tongue, and you'll find that—maybe, maybe not—the phrase in question means something other than what it did when you first heard it. It loses its poignancy because we, we are the ones who have become desensitized. I am going to say this: "God requireth that which is past" (Ecclesiastes 3:15) and if we're not clinging to and meditating on both the content of the word and also knowing Jesus—that which we've already received—then God can't give us those "new things". God wants to do that very thing: "behold I do a new thing; now it shall spring forth; shall ye not know it?" (Isaiah 43:19, emphasis mine) And as God teaches "precept upon precept, line upon line" (Isaiah 28:10), He is naturally (supernaturally?) going to require that we have both learned and know the lessons inherent in our experiences. The Holy Spirit is our teacher (see John 14:26). If we yield to Him in love, asking Him to teach us, then He will see to it that we know everything we need to regarding our call--our mission on this earth.
Everything old is new again.
