God's word is hidden from those who do not acknowledge Him! There are scores of prophecies about how and when Israel's Messiah ( Jesus) would come to them, but Israel missed the time of their visitation (Luke 19:43-44). God's secrets are only revealed through a relationship with Him!
Carefully consider this verse from I Cor 2:7-8
"but we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory: 8 which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory"
